———In the Linux kernel, the following vulnerability has been resolved:
media: video-i2c: use vb2_video_unregister_device on driver removal
The driver uses vb2_fop_release() as its file release operation, so
vb2_video_unregister_device() should be used instead of
video_unregister_device() during driver removal.
This ensures that the vb2 queue is properly disconnected before the
video device is unregistered.12hCVE-2026-98914——

net: thunderx: fix PTP device ref leak in nicvf_probe()
cavium_ptp_get() acquires a reference to the PTP PCI device
through pci_get_device(). If any initialization step fails
after cavium_ptp_get(), the PTP PCI device reference is leaked.

drm/amdgpu/userq: only accept doorbell BOs as queue doorbell
amdgpu_userq_get_doorbell_index() pins any BO passed as doorbell_handle
into the doorbell domain. For a regular BO, TTM moves it with
ttm_bo_move_null() and its contents are lost. Since an importer on the
same device gets the exporter's GEM object, a client can do this to a
buffer another client shared with it.
Reject BOs that were not created in the doorbell domain.

———In the Linux kernel, the following vulnerability has been resolved:
ALSA: seq: oss: Reject reads that cannot fit the next event
snd_seq_oss_read() checks whether the next queued OSS sequencer event
fits in the remaining userspace buffer before removing it from the read
queue.
The check is inverted. It currently stops when the event is smaller than
the remaining buffer, so a normal 4-byte event is not copied for an
8-byte read buffer. Conversely, an 8-byte event can be copied for a
smaller read count.
Break only when the remaining userspace buffer is smaller than the next
event, and report -EINVAL if no complete event has been copied. This
prevents an undersized read from looking like end-of-file while leaving
the event queued for a later read with a large enough buffer.12hCVE-2026-98911——
———In the Linux kernel, the following vulnerability has been resolved:
dpaa2-switch: fix the error path in dpaa2_switch_rx()
In case of an error in dpaa2_switch_rx(), the dpaa2_switch_free_fd()
function is called in order to free the FD. This is incorrect since the
dpaa2_switch_free_fd() is intended to be used on Tx frame descriptors,
meaning that it expects in the software annotation area of the FD data
to find a valid skb pointer on which to call dev_kfree_skb().
Fix this by extracting the dma_unmap_page() from
dpaa2_switch_build_linear_skb() directly into the dpaa2_switch_rx()
function. This allows us to directly use free_pages() in case of an
error before an SKB was created and kfree_skb() afterwards.12hCVE-2026-98910——
———In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Unwind debug trap enable on copy_to_user failure
If kfd_dbg_trap_enable() fails while copying runtime_info to userspace,
it had already activated the trap, set debug_trap_enabled, taken an extra
process reference, and opened the debug event file. Return -EFAULT without
unwinding that state, leaving inconsistent trap state and a refcount
imbalance that could break later DISABLE/ENABLE.
On copy_to_user failure, deactivate the trap and undo the rest of the
enable setup before returning.12hCVE-2026-98909——
———In the Linux kernel, the following vulnerability has been resolved:
net: cpsw_new: unregister devlink on port registration failure
cpsw_probe() registers devlink before registering the CPSW ports.
If cpsw_register_ports() fails, the error path only unregisters the
notifiers and then releases the lower level resources. It does not undo
the successful cpsw_register_devlink() call, leaving the devlink instance
and its parameters registered after probe has failed.
Add a devlink cleanup label for the path where devlink registration has
already succeeded, and use it when port registration fails.12hCVE-2026-98998——
———In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: th1520-dw-hdmi: Fix remove() callback
This driver stores struct th1520_hdmi * in platform drvdata, but
th1520_dw_hdmi_remove() was reading it back as struct dw_hdmi *
and passing it to dw_hdmi_remove(), so teardown runs on the wrong
pointer.
Retrieve struct th1520_hdmi * from platform drvdata and pass
hdmi->dw_hdmi to dw_hdmi_remove().11hCVE-2026-98908——
———In the Linux kernel, the following vulnerability has been resolved:
net: microchip: sparx5: clean up PSFP resources on flower setup failure
sparx5_tc_flower_psfp_setup() allocates PSFP stream gate, flow meter and
stream filter resources before adding VCAP actions. If a later step
fails, the resources allocated earlier in the function are not unwound.
Add error paths to release the stream filter, flow meter and stream gate
when setup fails after they have been acquired.
Also make sparx5_psfp_fm_add() return the acquired flow-meter id before
the existing-flow-meter early return. When an existing flow meter is
reused, sparx5_psfp_fm_get() increments its pool reference count, but the
caller previously kept psfp_fmid as 0. If a later setup step failed, the
error path could try to delete flow-meter id 0 instead of the reused flow
meter, leaving the incremented reference behind.12hCVE-2026-98907——
———In the Linux kernel, the following vulnerability has been resolved:
btrfs: protect sb_write_pointer() with invalidate lock
sb_write_pointer() reads the super block from the block device page cache
using read_cache_page_gfp(). This has the same race with BLKBSZSET as the
one fixed by commit 3f29d661e568 ("btrfs: sync read disk super and set
block size").
Take the mapping invalidate lock around read_cache_page_gfp() to
serialize the read against block size changes.12hCVE-2026-98999——
———In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix stale pinned_link entry when fb-pin performs the final unpin
xe_bo_pin_external() and xe_bo_unpin_external() maintain the bo's
pinned_link list membership in xe->pinned.late.external, based on
whether the current call is the outermost pin or the final unpin.
However, the same external bo's pin_count can also be raised and
lowered directly by __xe_pin_fb_vma()/__xe_unpin_fb_vma(), which pin
the bo as a display scanout buffer without going through
xe_bo_pin_external()/xe_bo_unpin_external() at all, and have no
notion of, or ownership over, pinned_link.
If a bo is pinned both externally (e.g. dma-buf export) and as an fb,
and the external unpin happens first, xe_bo_unpin_external() correctly
observes pin_count > 1 and leaves the bo on pinned_link. When the fb
unpin later performs the true last unpin (pin_count 1 -> 0), it never
touches pinned_link, leaving the bo linked on xe->pinned.late.external
indefinitely. Once the bo is subsequently freed, this stale list entry
points into freed memory, corrupting the list and risking a
use-after-free the next time the list is walked or spliced.
The backup object pin/unpin sites in xe_bo_notifier_prepare_pinned()/
xe_bo_notifier_unprepare_pinned() have the same bypass characteristic,
though they never add their bo to a pinned list, so are not affected
by this particular list-corruption issue.
Move the pinned_link removal into xe_bo_account_unpin(), which already
runs on every unpin path (kernel, external, framebuffer, backup
object) right before the true 1 -> 0 pin_count transition. Since
list_del_init() only operates on the node itself, this removal is
list-agnostic and safe to perform regardless of which list (external
or kernel_bo_present) the bo happens to be linked on, or which code
path is performing the final unpin. Drop the now-redundant explicit
list_del_init() calls in xe_bo_unpin_external() and xe_bo_unpin().
v2:
- New patch
v3:
- Rebased on changes to previous patch.

———In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix shrinker accounting double-subtraction on nested external pins
xe_bo_pin_external() and xe_bo_unpin_external() support nested pins,
since the underlying ttm_bo_pin()/ttm_bo_unpin() maintain a pin_count
refcount rather than a boolean. However, the shrinker accounting calls
xe_ttm_tt_account_subtract() and xe_ttm_tt_account_add() are invoked
unconditionally on every pin_external()/unpin_external() call, instead
of only on the transition into and out of the pinned state.
An external BO (dma-buf) can be pinned more than once while already
pinned, for example when it has multiple attachments/importers, each
independently calling xe_bo_pin_external(). Each such nested pin
subtracts the BO's pages from the shrinker's accounting again, even
though the BO's pages were already removed from consideration by the
first pin. Symmetrically, each nested unpin adds them back again
before the BO is actually unpinned. This desynchronizes the
shrinker's page and object counts from reality, and since they are
declared as signed long but interpreted as unsigned long in
xe_shrinker_count(), the underflow can turn into an enormous
shrinkable/purgeable page count, causing the shrinker to be invoked
excessively under memory pressure.
Guard the accounting calls with the same pin-count transition checks
already used to guard the pinned_link list maintenance, so accounting
is only updated on the outermost pin and the final unpin.
While centralizing this logic into xe_bo_account_pin()/
xe_bo_account_unpin(), also close a second, related accounting gap
affecting imported dma-bufs. For an imported bo's ttm_tt, xe's
ttm_tt_populate hook (xe_ttm_tt_populate()) early-returns without
calling xe_ttm_tt_account_add(), since TTM_TT_FLAG_EXTERNAL is set
without TTM_TT_FLAG_EXTERNAL_MAPPABLE. However, TTM core's
ttm_tt_populate() wrapper unconditionally marks the tt as populated
on driver-hook success, so ttm_tt_is_populated() still reports true
for it. xe_bo_account_pin()/xe_bo_account_unpin() trusted
ttm_tt_is_populated() as a proxy for "these pages are accounted for
by the shrinker", and would subtract/add pages for such a tt that
were never added in the first place, again underflowing the
shrinker's counts. This is reachable today via xe_bo_pin_external(),
and would have become newly reachable via the fb-pin path once this
patch routes __xe_pin_fb_vma() through xe_bo_pin_account() below, so
fix it here rather than in a later patch, to avoid a commit in this
series that introduces the regression before fixing it. Skip the
accounting for imported bos, using the same EXTERNAL &&
!EXTERNAL_MAPPABLE test xe_ttm_tt_populate()/xe_ttm_tt_unpopulate()
use to decide whether to act, via a new xe_ttm_bo_is_imported()
helper (hoisted up from its only prior use site).
v2:
- Fix the critical issue caught by Sashiko AI review: the pin-count
transition check introduced here was still bypassed by the fb-pin
path (__xe_pin_fb_vma()/__xe_unpin_fb_vma()), which could leave a
stale pinned_link entry and a permanent shrinker accounting leak
when the fb-unpin performed the true last unpin. Addressed in a
separate follow-up patch in this series rather than folded in here,
since it is a distinct bug with its own Fixes: tag.
- Drop the unneeded local "last_unpin" variable in
xe_bo_unpin_external(), restoring the original inline
bo->ttm.pin_count == 1 check; it was a no-op rename not used by any
of the new accounting helpers, and was going to be deleted again by
the follow-up patch anyway.
v3:
- Exclude imported dma-bufs from the pin/unpin shrinker accounting,
fixing another underflow caught by Sashiko AI review.
- Add a short comment on the backup-object pin site noting it's
already populated/accounted at pin time, addressing (as a
false-positive clarification, no code fix needed) a separate
Medium-severity accounting-leak concern also caught by Sashiko AI

———In the Linux kernel, the following vulnerability has been resolved:
net: lan966x: restore RX state on reload failure
lan966x_fdma_reload() backs up rx->page_pool and rx->fdma before
reallocating the RX resources for the new MTU. If the allocation fails,
the restore path puts these fields back before restarting RX.
However, the reload path also updates rx->page_order and rx->max_mtu
before calling lan966x_fdma_rx_alloc(). These fields are not restored on
failure, so RX can be restarted with the old pages, old FDMA state and
old page pool, but with the page geometry from the failed new MTU.
This can make the XDP path advertise a frame size derived from the new
page_order while the actual RX pages still come from the old allocation.
For example, after a failed reload to a jumbo MTU, xdp_init_buff() may be
called with a frame size larger than the restored RX pages.
lan966x_fdma_rx_alloc_page_pool() also registers the newly allocated page
pool with each port's XDP RXQ before fdma_alloc_coherent() is called. If
fdma_alloc_coherent() fails, the new page pool is destroyed, but the
rollback path does not restore the per-port XDP RXQ mem model
registration either.
Save and restore rx->page_order and rx->max_mtu, and restore the old page
pool registration for each port's XDP RXQ before RX is started again.
This keeps the restored RX state consistent after a failed reload.12hCVE-2026-98905——

drm/amdkfd: Properly acquire queue buffers in CRIU restore
When kfd_queue_acquire_buffers() was split off from
set_queue_properties_from_user(), set_queue_properties_from_criu()
was missed. Thus, set_queue_properties_from_criu() is not
filling out the buffer fields of queue_properties, which
can come up when subsequent code expects them to be non-null.
Add the proper call to kfd_queue_acquire_buffers(), and also
use the right cast types in set_queue_properties_from_criu()
(which were missed at the same time)

———A cross-site request forgery vulnerability in the OAuth extension of Zimbra Collaboration Suite (ZCS) Network Edition allows an attacker to link an attacker-controlled external account to a victim's mailbox. The OAuth callback does not bind its state value or authorization code to the initiating Zimbra session and instead selects the destination mailbox from the browser's current authentication cookie. On a deployment with the provider configured, an attacker can induce a signed-in victim to load a callback containing a fresh code for the attacker's provider account. This creates a persistent data source that imports attacker-controlled contacts or events. With bidirectional CalDAV synchronization, appointments subsequently created or edited in the linked calendar are also disclosed to the attacker. ZCS 10.1.16 and 10.1.20 are affected.7hCVE-2026-98904——
———In the Linux kernel, the following vulnerability has been resolved:
mailbox: imx: Use devm_pm_runtime_enable()
sashiko complained about early usage of the device while probe isn't
completed. This can be mitigated by delaying the pm_runtime_enable()
into the removal path instead doing it early. This ensures that in an
error case the device is removed (and imx_mu_shutdown()) before
pm_runtime_disable() so we don't have to do this manually.
For the order to work, lets move devm_mbox_controller_register() until
after the pm-runtime part. So the reverse order will be mbox-controller
removal followed by disabling pm runtime.
Use devm_pm_runtime_enable(), remove manual pm_runtime_disable()
invocations and move the pm_runtime handling in probe before
devm_mbox_controller_register().12hCVE-2026-98903——

imx_mu_isr() imx_mu_shutdown()
imx_mu_xcr_rmw(priv, IMX_MU_RCR, 0, IMX_MU_xCR_RIEn(priv->dcfg->type, cp->idx));
imx_mu_specific_rx()
imx_mu_xcr_rmw(priv, IMX_MU_RCR, IMX_MU_xCR_RIEn(priv->dcfg->type, 0), 0);
free_irq()
The RX event remains enabled because in this short window the RX event
was disabled in ->shutdown() while the interrupt was active and then
enabled again by the ISR while ->shutdown waited in free_irq().
This race requires timing and if happens can be problematic on shared
handlers if the "removed" channel triggers an interrupt. In this case
the irq-core will shutdown the interrupt with the "nobody cared"
message.
Introduce imx_mu_con_priv::shutdown to signal that the channel is
shutting down. This flag is set with the lock held (by
imx_mu_xcr_clr_shut()). The unmask side uses imx_mu_xcr_set_act() which
only enables the event if the channel has not been shutdown and
serialises on the same lock.12hCVE-2026-936335.4 MED—
———A CSS sanitization vulnerability in Zimbra Collaboration Suite (ZCS) allows an authenticated user with Briefcase access to publish a document that displays attacker-controlled content under the Zimbra origin. When processing a stylesheet containing non-ASCII characters, DefangFilter appends the final ASCII segment without sanitizing it. HTML stored as application/x-zimbra-doc can therefore retain CSS URL references that the normal sanitizer removes. An attacker can share a crafted document that loads external resources and displays a credential-collection form using Zimbra's own visual assets. Exploitation requires the victim to open the document in a browser that renders the content type inline; credential theft additionally requires form submission. ZCS 10.1.16 and 10.1.20 are affected.7hCVE-2026-98902——

———In the Linux kernel, the following vulnerability has been resolved:
drm/xe/i2c: cancel the client work on remove
xe_i2c_notifier() stores the DesignWare adapter in i2c->adapter and
schedules i2c->work when the adapter is registered under the xe I2C
platform device, and xe_i2c_client_work() then instantiates the AMC
client device on that adapter.
xe_i2c_remove() tears down the AMC, unregisters the client devices,
the bus notifier and the adapter platform device, but it never drains
i2c->work. A work item that is still queued or running when the
adapter is unregistered dereferences i2c->adapter in
i2c_new_client_device() after platform_device_unregister() has
released the adapter. The work item is also embedded in the
devm-allocated struct xe_i2c, so a work item still queued after the
drm device devm unwind frees that allocation runs its callback on
freed memory.
The bus notifier is the only thing that schedules this work, and it is
unregistered after the client devices. An instance that is still queued
when the teardown runs can therefore write
i2c->client[XE_I2C_CLIENT_AMC] while the loop is unregistering and
clearing the same array, and an AMC client it instantiates late is only
cleaned up by the adapter's own child sweep in i2c_del_adapter().
Move bus_unregister_notifier() in front of the client teardown loop
and cancel the work right after it, so no new instance can be
scheduled and a queued instance is drained before the client array is
touched. A running instance still finds a live adapter, since the
adapter is unregistered later.

———In the Linux kernel, the following vulnerability has been resolved:
ksmbd: don't hold ci->m_lock while waiting for a lease break ack
When a cifs.ko client caches a read-handle (RH) lease via deferred close
and a conflicting open arrives, ksmbd breaks the lease and waits for the
acknowledgment in wait_for_break_ack() for up to OPLOCK_WAIT_TIME (35s).
__smb_break_all_levII_oplock() runs that wait while holding ci->m_lock
for read.
cifs.ko reacts to a handle-lease break by closing the deferred handle
rather than sending a lease break acknowledgment. That close path
(close_id_del_oplock() -> opinfo_del()) takes ci->m_lock for write and
is exactly what would wake the waiter, but it blocks on the read lock
held by the waiting thread. The break is then resolved only by the 35s
timeout, so xfstests generic/001 takes ~78s with leases enabled versus
~4s with oplocks only.
Collect the target opinfos (each pinned with a reference) while holding
ci->m_lock, then break them after releasing it, matching how
smb_grant_oplock() already breaks a conflicting lease using only a
reference. The reference keeps the opinfo (and its conn and lease)
alive across the unlocked window, and a close racing the break is
handled by the existing OPLOCK_CLOSING state check. Apply the same fix
to the parent lease break paths.12hCVE-2026-98896——

———In the Linux kernel, the following vulnerability has been resolved:
drm/amd/ras: reset CPER ring on corrupt entry size
When CPER ring overflow handling advances the read pointer, it trusts the
parsed entry size from the current ring contents. Corrupt CPER data can
produce an entry size that does not advance rptr after dword conversion
and pointer masking.
In that case the recovery loop keeps testing the same location while
holding the CPER ring mutex. This can hang the worker that is writing the
next CPER record.
Detect a no-progress rptr update and reset the CPER ring to an empty
state instead. This drops the corrupt contents and lets the writer leave
