CVE-2026-68233—

—

———In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Shut down BO cache timer before teardown The BO cache timer callback schedules time_work, and time_work can rearm the timer through vc4_bo_cache_free_old(). vc4_bo_cache_destroy() deletes the timer and then cancels the work, which does not break that cycle: the work being cancelled can rearm the timer, and the timer then queues work again after teardown. Use timer_shutdown_sync() instead, so the timer cannot be rearmed and the cycle ends with cancel_work_sync().8h CVE-2026-68103—

———In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject mapping a reserved doorbell to a new queue When creating an user-queue, the user space provides a doorbell BO handle and an offset within the bo to obtain a doorbell. However current implementation using xa_store_irq() to store a doorbell, which allows a later queue created with the same BO and offset parameters to overwrite an existing queue and doorbell mapping. This can cause problems like misrouting fence IRQ processing to a wrong queue, and mislead the cleanup process of one queue erasing the mapping of another queue. This commit fixes this issue by replacing xa_store_irq with xa_insert_irq, which rejects mapping a reserved doorbell to a newly created queue (cherry picked from commit 6244eae22966350db52faf9c1369d3b2ffc5de4e)8h CVE-2026-68104—

———In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: invoke pm_genpd_remove() before freeing genpd Call pm_genpd_remove() to unregister from global list prior to releasing acp_genpd memory, and clear the pointer after free. (cherry picked from commit cd8650d7a91ee8b768e202354672553faa5cc1f2)8h CVE-2026-68232—

———In the Linux kernel, the following vulnerability has been resolved: drm/gpusvm: Fix MM reference leak in drm_gpusvm_range_evict If kvmalloc_array() fails in drm_gpusvm_range_evict(), the MM reference acquired earlier is not released, resulting in a reference leak. Fix this by dropping the MM reference on the kvmalloc_array() failure path.8h CVE-2026-68231—

—

———In the Linux kernel, the following vulnerability has been resolved: media: airspy: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. airspy_start_streaming() returned -ENODEV early when the USB device had been disconnected (s->udev == NULL) without returning any buffers that buf_queue() had already accepted. Take v4l2_lock first and jump to the existing err_clear_bit label, which already drains s->queued_bufs via vb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking. This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure").8h CVE-2026-68230—

———In the Linux kernel, the following vulnerability has been resolved: media: amlogic-c3: Add validations for ae and awb config Avoid invalid memory access if the zones_num is bigger than zone_weight. This patch fixes the following smatch errors: drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:111 c3_isp_params_awb_wt() error: buffer overflow 'cfg->zone_weight' 768 <= u32max drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:111 c3_isp_params_awb_wt() error: buffer overflow 'cfg->zone_weight' 768 <= u32max drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:227 c3_isp_params_ae_wt() error: buffer overflow 'cfg->zone_weight' 255 <= u32max drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:227 c3_isp_params_ae_wt() error: buffer overflow 'cfg->zone_weight' 255 <= u32max8h CVE-2026-68229—

—

———In the Linux kernel, the following vulnerability has been resolved: media: cedrus: skip invalid H.264 reference list entries Cedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the stateless slice control and later uses their indices to look up decode->dpb[] in _cedrus_write_ref_list(). Rejecting such controls in cedrus_try_ctrl() would break existing userspace, since stateless H.264 reference lists may legitimately carry out-of-range indices for missing references. Instead, guard the actual DPB lookup in Cedrus and skip entries whose indices do not fit the fixed V4L2_H264_NUM_DPB_ENTRIES array. This keeps the fix local to the driver use site and avoids out-of-bounds reads from malformed or unsupported reference list entries.8h CVE-2026-68228—

—

———In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Move src_buf Removal to finish_encode During encoder processing, there is a case where the IRQ response could return the buffer back to userspace via v4l2_m2m_buf_done call. In this time, userspace could queue up this same buffer before start_encode removes the index from the ready queue. This would then lead to a case where the buffer in the ready queue could be a self loop due to the WRITE_ONCE(prev->next, new) call in __list_add. When __list_del is finally called, the loop is already made so nothing points back to ready queue list head and pointers are poisoned. A buffer should not be marked as DONE before the buffer is removed from m2m ready queue. Move removal entirely to finish_encode.8h CVE-2026-68227—

—

———In the Linux kernel, the following vulnerability has been resolved: media: cx231xx: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers are unbound without their devices being physically disconnected (e.g. on probe deferral or configuration changes). Fix the driver state lifetime so that it is released on driver unbind.8h CVE-2026-68226—

—

———In the Linux kernel, the following vulnerability has been resolved: media: cx23885: add ioremap return check and cleanup Add a check for the return value of pci_ioremap_bar() in cx23885_dev_setup(). If ioremap for BAR0 fails, release the already allocated PCI memory region, decrement the device count, and return -ENODEV. This prevents a potential null pointer dereference and ensures proper cleanup on memory mapping failure.8h CVE-2026-68225—

—

———In the Linux kernel, the following vulnerability has been resolved: media: i2c: alvium: fix critical pointer access in alvium_ctrl_init The current implementation of alvium_ctrl_init creates several controls in function alvium_ctrl_init and uses the returned pointer without check. That can cause write access over NULL-pointer for several controls. The reworked code checks the pointers before adding flags.8h CVE-2026-68224—

—

———In the Linux kernel, the following vulnerability has been resolved: media: mali-c55: Fix possible ERR_PTR in enable_streams The media_pad_remote_pad_unique() function returns either a valid pointer or an ERR_PTR() on failure (-ENOTUNIQ if multiple links are enabled, -ENOLINK if no connected pad is found). The return value was assigned directly to isp->remote_src and dereferenced in the next line without checking for errors, which could lead to an ERR_PTR dereference. Add proper error checking with IS_ERR() before dereferencing the pointer. Also set isp->remote_src to NULL on error to maintain consistency with other error paths in the function.8h CVE-2026-68223—

—

———In the Linux kernel, the following vulnerability has been resolved: media: meson: vdec: Fix memory leak in error path of vdec_open The vdec_open() function previously jumped directly to err_m2m_release when vdec_init_ctrls() failed, skipping release of the m2m context. This caused a resource leak. Fix it by introducing a proper err_m2m_ctx_release label that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before releasing the m2m device. This was identified via kmemleak: unreferenced object 0xffff0000205d6878 (size 8): comm "v4l_id", pid 5289, jiffies 4294938580 hex dump (first 8 bytes): 40 d2 49 18 00 00 ff ff @.I..... backtrace (crc d3204599): kmemleak_alloc+0xc8/0xf0 __kvmalloc_node_noprof+0x60c/0x850 v4l2_ctrl_handler_init_class+0x1b4/0x2e8 [videodev] vdec_open+0x1f4/0x788 [meson_vdec] v4l2_open+0x144/0x460 [videodev] chrdev_open+0x1ac/0x500 do_dentry_open+0x3f0/0xfe8 vfs_open+0x68/0x320 do_open+0x2d8/0x9a8 path_openat+0x1d0/0x4f0 do_filp_open+0x190/0x380 do_sys_openat2+0xf8/0x1b0 __arm64_sys_openat+0x13c/0x1e8 invoke_syscall+0xdc/0x268 el0_svc_common.constprop.0+0x178/0x258 do_el0_svc+0x4c/0x708h CVE-2026-68222—

———In the Linux kernel, the following vulnerability has been resolved: media: msi2500: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. msi2500_start_streaming() had five error paths that all hit this trap and were further tangled by ret-overwriting between calls: - -ENODEV when the USB device was already disconnected - -ERESTARTSYS when mutex_lock_interruptible() was interrupted - msi2500_set_usb_adc() failure: ret was silently overwritten by the next call (msi2500_isoc_init), so the error was lost entirely - msi2500_isoc_init() failure: cleanup_queued_bufs was called, but the function then fell through to msi2500_ctrl_msg() and again masked the original error by overwriting ret - msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all, leaving isoc URBs submitted with no way for the driver to consume them Consolidate the error paths into a small goto chain. Every failure now stops the function, drains the queued-buffer list, and returns the real error code. The ctrl_msg failure path also rolls back the preceding msi2500_isoc_init() via msi2500_isoc_cleanup() before unlocking and draining. The cleanup helper takes a vb2_buffer_state argument so that the start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as expected by userspace on start_streaming failure) while stop_streaming keeps its existing VB2_BUF_STATE_ERROR semantics. This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure").8h CVE-2026-68221—

—

———In the Linux kernel, the following vulnerability has been resolved: media: nuvoton: npcm-video: fix memory leaks in probe and remove npcm_video_probe() allocates the npcm_video structure with kzalloc_obj() but never frees it on any probe error path or in npcm_video_remove(), leaking the allocation on every failed probe and every normal unbind. Additionally, when npcm_video_setup_video() fails, the reserved memory association established by of_reserved_mem_device_init() in npcm_video_init() is not released, leaking the rmem_assigned_device entry on the global list. Fix both by adding kfree(video) to all probe error paths and to npcm_video_remove(), and adding the missing of_reserved_mem_device_release() call when npcm_video_setup_video() fails.8h CVE-2026-68220—

—

———In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe Both mxc_isi_crossbar_init() and mxc_isi_pipe_init() call v4l2_subdev_init_finalize() which allocates the subdev active state, but neither mxc_isi_crossbar_cleanup() nor mxc_isi_pipe_cleanup() calls v4l2_subdev_cleanup() to free it. This causes a memory leak on every rmmod, reported by kmemleak: unreferenced object 0xffff0000d06fc800 (size 192): comm "(udev-worker)", pid 254, jiffies 4294913455 backtrace (crc 36eeae58): kmemleak_alloc+0x34/0x40 __kvmalloc_node_noprof+0x5f8/0x7d8 __v4l2_subdev_state_alloc+0x1fc/0x30c __v4l2_subdev_init_finalize+0x178/0x368 Add the missing v4l2_subdev_cleanup() calls before media_entity_cleanup() in both crossbar and pipe cleanup paths.8h CVE-2026-68219—

———In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Fix potential out-of-bounds issues The maximum downscaling factor supported by ISI can be up to 16. Add minimum value constraint before applying the setting to hardware. Otherwise, the process will not respond even when Ctrl+C is executed.8h CVE-2026-68218—

—

———In the Linux kernel, the following vulnerability has been resolved: media: pwc: Drain fill_buf on start_streaming() failure pwc_isoc_init() submits its isochronous URBs with usb_submit_urb(.., GFP_KERNEL) in a loop. After the first URB is submitted, its completion handler pwc_isoc_handler() can run on another CPU before the loop finishes: start_streaming() pwc_isoc_init() usb_submit_urb(urbs[0], GFP_KERNEL) pwc_isoc_handler(urbs[0]) pdev->fill_buf = pwc_get_next_fill_buf(pdev) usb_submit_urb(urbs[i>0], ..) -> fails pwc_isoc_cleanup(pdev) /* kills URBs */ return ret; pwc_cleanup_queued_bufs(pdev, VB2_BUF_STATE_QUEUED) pwc_get_next_fill_buf() detaches a buffer from pdev->queued_bufs and stores it in pdev->fill_buf. The error path in start_streaming() only drains pdev->queued_bufs, so the buffer parked in pdev->fill_buf is leaked. vb2_start_streaming() then triggers WARN_ON(owned_by_drv_count). stop_streaming() already handles this since commit 80b0963e1698 ("[media] pwc: fix WARN_ON"), which added the fill_buf drain in the teardown path but not in the start_streaming() error path. Mirror that handling on failure so start_streaming() returns with no buffer owned by the driver. Issue identified by automated review of the INV-003 series at https://sashiko.dev/8h CVE-2026-68216—

—

———In the Linux kernel, the following vulnerability has been resolved: media: pwc: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. pwc's start_streaming() had two early returns that hit this trap: -ENODEV when the USB device was already disconnected, and -ERESTARTSYS when mutex_lock_interruptible() was interrupted by a signal. Call the existing pwc_cleanup_queued_bufs() helper with VB2_BUF_STATE_QUEUED before returning (matching the state already used by the pwc_isoc_init() error path in the same function). This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure").8h CVE-2026-68215—

—

———In the Linux kernel, the following vulnerability has been resolved: media: radio-si476x: Unregister v4l2_device on probe failure si476x_radio_probe() registers radio->v4l2dev before allocating the V4L2 controls and before registering the video device. If any of those later steps fails, probe returns through the exit label after freeing only the control handler. A failed probe does not call si476x_radio_remove(), so the v4l2_device_unregister() there is not reached. This leaves the parent device reference taken by v4l2_device_register() behind on the error path. Unregister the V4L2 device in the probe error path after freeing the controls.8h CVE-2026-68214—

—

———In the Linux kernel, the following vulnerability has been resolved: media: rtl2832: fix use-after-free in rtl2832_remove() cancel_delayed_work_sync() is called before i2c_mux_del_adapters() in rtl2832_remove(). While the cancel waits for any running instance of i2c_gate_work to finish, it does not prevent the timer from being rescheduled by a concurrent thread. During probe, the r820t_attach() call attempts I2C transfers through the mux adapter. These transfers go through i2c_mux_master_xfer(), which calls rtl2832_deselect() after the transfer completes, rescheduling i2c_gate_work via schedule_delayed_work(). If this transfer is still in flight when rtl2832_remove() runs, rtl2832_deselect() can reschedule i2c_gate_work after it has been cancelled, causing a use-after-free when kfree(dev) is called. Fix this by calling i2c_mux_del_adapters() before cancel_delayed_work_sync(). Once the mux adapter is unregistered, no new I2C transfers can go through it, so rtl2832_deselect() can no longer reschedule i2c_gate_work. The subsequent cancel_delayed_work_sync() is then guaranteed to be final.8h CVE-2026-68213—

———In the Linux kernel, the following vulnerability has been resolved: media: rtl2832_sdr: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. rtl2832_sdr_start_streaming() had multiple error paths that hit this trap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six `goto err` paths covering subdev s_power, tuner setup, ADC setup, stream-buffer allocation, urb allocation, and urb submission failures. None of them returned the queued buffers. The original function had no distinct success exit and fell straight through into the err label, which previously only did mutex_unlock and "return ret". Adding queued-buffer cleanup at err must therefore be paired with an explicit success return; otherwise every successful start would also drain the buffer queue and kill streaming. Add that success return, then add rtl2832_sdr_cleanup_queued_bufs() at the err label and before each early return. The cleanup helper takes a vb2_buffer_state argument so that the start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as expected by userspace on start_streaming failure) while stop_streaming keeps its existing VB2_BUF_STATE_ERROR semantics. This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure"). The err label still does not roll back power_ctrl(), frontend_ctrl(), the POWER_ON flag, or stream/URB allocations that may have happened before the failing step. Those are pre-existing leaks of a different class and are not addressed here.8h CVE-2026-68212—

—

———In the Linux kernel, the following vulnerability has been resolved: media: saa7134: Fix a possible memory leak in saa7134_video_init1 In saa7134_video_init1(), the return value of the first saa7134_pgtable_alloc() is not checked. If it fails, the function continues as if successful, leaving the driver with an invalid page table. Additionally, if vb2_queue_init() for the VBI queue fails after the video queue page table has been allocated, the allocated memory is not freed before returning. The second saa7134_pgtable_alloc() also lacks a return value check. Errors occur during device probing before the device is fully registered, the normal cleanup path in saa7134_finidev() is not executed, leading to memory leaks and potential use of uninitialized DMA resources. Check the return value of both saa7134_pgtable_alloc() calls and propagate errors. On failure of any later step, free allocated page tables to avoid memory leaks. Ensure control handlers are also released on error to prevent further resource leakage. Found by code review.8h CVE-2026-68211—

—

———In the Linux kernel, the following vulnerability has been resolved: media: stm32-dcmipp: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. dcmipp_bytecap_start_streaming() returned -EINVAL when the source subdevice could not be resolved from the media graph, before pm_runtime_resume_and_get() and media_pipeline_start() had been called. The remaining error paths already converge on the err_buffer_done label, which calls dcmipp_bytecap_all_buffers_done(..., VB2_BUF_STATE_QUEUED). Jump to that label directly: the intermediate err_pm_put / err_media_pipeline_stop labels are skipped, which is correct because nothing they would undo has happened yet. This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure").8h CVE-2026-68210—

—

———In the Linux kernel, the following vulnerability has been resolved: media: stm32: dcmi: unregister notifier on probe failure dcmi_graph_init() registers the async notifier before dcmi_probe() toggles the reset line. If reset_control_assert() or reset_control_deassert() fails afterwards, probe returns through err_cleanup and the driver core will not call dcmi_remove(). Unregister the notifier before cleaning it up on that error path, matching the successful remove path and the V4L2 async notifier lifetime rules. [hverkuil: added Fixes tag]8h CVE-2026-68209—

—

———In the Linux kernel, the following vulnerability has been resolved: media: sun4i-csi: Return queued buffers on start_streaming() failure The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming(). If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak. sun4i_csi_start_streaming() returned -EINVAL when no matching CSI format could be found, before any setup (scratch buffer allocation, pipeline start) had been performed. The remaining error paths already converge on the err_clear_dma_queue label, which calls return_all_buffers(..., VB2_BUF_STATE_QUEUED) under csi->qlock. Jump to that label directly: the intermediate err_disable_device / err_disable_pipeline / err_free_scratch_buffer labels are skipped, which is correct because nothing they would undo has happened yet. This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo: Return queued buffers on start_streaming() failure").8h CVE-2026-68208—

———In the Linux kernel, the following vulnerability has been resolved: media: ti: vpe: Fix the error code of devm_kzalloc() in vip_probe_slice() In vip_probe_slice(), the error check for devm_kzalloc() incorrectly uses PTR_ERR_OR_ZERO() which returns 0 for NULL pointer.

—

———In the Linux kernel, the following vulnerability has been resolved: media: ti: vpe: unwind v4l2 device registration on probe error If the vpe_top resource is missing, vpe_probe() returns -ENODEV after v4l2_device_register() has succeeded. Probe failures do not call the driver's remove callback, so the v4l2 device remains registered on that error path. Route that failure through the existing v4l2_device_unregister() unwind label, matching the other errors after v4l2_device_register().8h CVE-2026-68206—

—

———In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC active reference counts HEVC slice parameters are shared stateless V4L2 controls, but the common validation path does not verify the active L0/L1 reference counts before driver-specific code consumes them. The original report came from Cedrus, but the active count bounds are not Cedrus-specific. Validate them in the common HEVC slice control path so stateless HEVC drivers get the same basic guarantees as soon as the control is queued. Do not reject ref_idx_l0/ref_idx_l1 entries here. Existing userspace may use out-of-range sentinel values such as 0xff for missing references, and some hardware can use that information for concealment. Keep this common check limited to the active reference counts.8h CVE-2026-68205—

—

———In the Linux kernel, the following vulnerability has been resolved: media: vivid: check for vb2_is_busy() when toggling caps The vivid_update_format_cap/out() functions must only be called if the capture/output queue are not busy. But for the controls that select the CROP/COMPOSE/SCALE capability that is not checked. Only when streaming starts will they be set to 'grabbed' and it is impossible to change the control, but between REQBUFS and STREAMON you are still allowed to set these controls. Since vivid_update_format_cap/out will change the format, this can cause unexpected results. Besides adding these checks, also add a WARN_ON in vivid_update_format_cap/out() if the queue is busy. I'm 90% certain that this is the cause of this syzbot bug: https://syzkaller.appspot.com/bug?extid=dac8f5eaa46837e97b89 But since we never have reproducers, it is hard to be certain. In any case, these checks are needed regardless.8h CVE-2026-68203—

—

———In the Linux kernel, the following vulnerability has been resolved: media: vivid: fix cleanup bugs in vivid_init() When platform_device_register() fails in vivid_init(), the embedded struct device in vivid_pdev has already been initialized by device_initialize(), but the failure path jumps to free_output_strings without dropping the device reference for the current platform device: vivid_init() -> platform_device_register(&vivid_pdev) -> device_initialize(&vivid_pdev.dev) -> setup_pdev_dma_masks(&vivid_pdev) -> platform_device_add(&vivid_pdev) This leads to a reference leak when platform_device_register() fails. Fix this by calling platform_device_put() before jumping to the common cleanup path. Also, the unreg_driver label incorrectly calls platform_driver_register() instead of platform_driver_unregister(), which breaks cleanup when workqueue creation fails after successful driver registration. Fix that as well. The reference leak was identified by a static analysis tool I developed and confirmed by manual review. The incorrect cleanup call was found during code inspection.8h CVE-2026-68202—

—

———In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: close a re-opened queue timer in the destructor queue_delete() closes the queue timer, then frees it. snd_seq_timer_close() clears q->timer->timeri. snd_use_lock_sync() then drains borrowers, and snd_seq_timer_delete() frees q->timer. A borrower can re-open the timer inside that window. A SET_QUEUE_CLIENT that took a queueptr() use_lock reference before the queue was unlinked runs snd_seq_timer_open() after the close. Open refuses re-open only while timeri is set, and the close just cleared it, so it re-opens timeri. snd_seq_timer_delete() does not close that instance. Its snd_seq_timer_stop() is a no-op, because running was cleared first. So it frees q->timer with the instance still live. The queue is freed next. The instance stays on the global timer with callback_data pointing at the freed queue. A non-owner START on the unlocked queue arms it. The next tick derefs the freed queue in snd_seq_timer_interrupt(). Reachable by an unprivileged user with access to /dev/snd/seq. No CAP and no queue ownership required. Close any lingering instance in the destructor. There, ->timeri can no longer change: the queue is unlinked and all use_lock borrowers have drained, so no snd_seq_queue_use() can re-open it. Close it before clearing q->timer. snd_timer_close() waits for any in-flight snd_seq_timer_interrupt() to finish, and that callback still reads q->timer (via snd_seq_check_queue()), so q->timer must stay valid until it drains.8h CVE-2026-68105—

———In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: drain a slave's callback before its master detaches it snd_timer_close_locked() drains the closing instance's own in-flight callback (IFLG_CALLBACK) before freeing it, but not its slaves'. When a master instance is closed, remove_slave_links() clears each slave's ->timer; the slave's own close then reads timer == NULL and takes the branch that skips the drain entirely (snd_timer_stop_slave() also no-ops on a NULL timer). So a slave whose callback is still running when the master is closed is freed underneath the live callback, leading to use-after-free. Drain the slaves too before remove_slave_links() severs them. snd_timer_stop() has already taken this instance off the active list, so no new slave callback can be queued. Take the slaves off the ack list so a pending one can't fire either, then wait for any that is already in flight.8h CVE-2026-68200—

———In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: don't re-enter an instance callback that is still running The userspace-driven timer (utimer) TRIGGER ioctl calls snd_timer_interrupt() directly with no serialization, so two threads triggering the same utimer can run snd_timer_interrupt() on one snd_timer concurrently. snd_timer_process_callbacks() drops timer->lock around each instance callback and marks the in-flight callback with the single SNDRV_TIMER_IFLG_CALLBACK bit; snd_timer_close_locked() waits on that bit to drain an in-flight callback before freeing the instance. The bit cannot represent two concurrent callbacks: when a second interrupt re-queues an instance whose callback is still running, both run at once, the first to finish clears the bit, and the close-path drain then frees the instance (and its callback_data) while the other callback is still live - a use-after-free reachable by any user able to open /dev/snd/timer, both via a user timer instance and via a sequencer queue timer bound to the utimer. snd_timer_interrupt() sets IFLG_CALLBACK before dropping timer->lock, so a concurrent interrupt already observes it under the lock. Skip re-queuing an instance (and its slaves) to the ack/sack list while its callback is in flight; the accumulated pticks are delivered on the next tick, so no event is lost.8h CVE-2026-68199—

———In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB access from firmware ADDBA window size aggr_recv_addba_req_evt() logs a debug message when the firmware-supplied win_sz is outside [AGGR_WIN_SZ_MIN, AGGR_WIN_SZ_MAX] but does not return. The out-of-range win_sz is then used in TID_WINDOW_SZ() to compute a kzalloc size and stored in rxtid->hold_q_sz, leading to zero-size or overflowed allocations and subsequent out-of-bounds access. Clean up any previously active aggregation session for the TID first, then return early when win_sz is out of the valid range, instead of proceeding with a broken allocation size.8h CVE-2026-68198—

———In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix use-after-free in aggr_reset_state() The aggr_reset_state() function uses timer_delete() (non-synchronous) for the aggregation timer before proceeding to delete TID state and before the structure is freed by callers like aggr_module_destroy(). If the timer callback (aggr_timeout) is executing when aggr_reset_state() is called, the callback will continue to access aggr_conn fields like rx_tid[] and stat[] which may be freed immediately after by kfree(aggr_info->aggr_conn) in aggr_module_destroy(). Additionally, the timer callback can re-arm itself via mod_timer() while aggr_reset_state() is running, creating a more complex race condition. Use timer_delete_sync() instead to ensure any running timer callback has completed before returning.8h CVE-2026-68197—

———In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: fix NULL dereference when the AP has HT-cap but no HT-oper mwifiex_tdls_add_ht_oper() gates its follow-the-AP-bandwidth path on bss_desc->bcn_ht_cap being present, but then dereferences a different pointer, bss_desc->bcn_ht_oper: if (ISSUPP_CHANWIDTH40(priv->adapter->hw_dot_11n_dev_cap) && bss_desc->bcn_ht_cap && ISALLOWED_CHANWIDTH40(bss_desc->bcn_ht_oper->ht_param)) bcn_ht_cap and bcn_ht_oper are populated independently while parsing the associated AP's beacon in mwifiex_update_bss_desc_with_ie(): an AP that advertises an HT Capabilities element but no HT Operation element leaves bcn_ht_cap non-NULL and bcn_ht_oper NULL. Setting up a TDLS link to a peer while associated to such an AP then dereferences the NULL bcn_ht_oper and crashes the kernel. Every other bcn_ht_oper user in the driver NULL-checks it first. Guard on the pointer that is actually dereferenced. Found by 0sec automated security-research tooling (https://0sec.ai).8h
