CVE-2026-571787.4 HIG4.8%
——1Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the `vk-app` backend accepted VK application callback data without verifying the callback signature when the `auth_key` parameter was omitted. Applications using this backend could treat unsigned attacker-controlled data as a verified VK identity. An attacker could choose callback fields such as `viewer_id`, `access_token`, `api_id`, and `api_result`, potentially allowing authentication as an arbitrary VK user ID. The issue affects only applications using the `vk-app` backend. The issue has been fixed in version 5.0.0 by requiring `auth_key` to be present and valid before callback data is trusted.22dCVE-2026-571774.3 MED1.1%
——0Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the LoginRadius backend did not validate OAuth state during the authentication flow. Applications using this backend were vulnerable to login CSRF. An attacker could cause a victim's browser session to complete authentication using an attacker-controlled LoginRadius token, making the victim authenticated as the attacker's LoginRadius identity. The issue affects only applications using the LoginRadius backend. The issue has been fixe in version 5.0.0 by enabling callback state validation for the LoginRadius backend.15dCVE-2026-571766.8 MED11.6%
——3Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the Vend OAuth2 backend used only the numeric Vend user_id as the social-auth UID. When multiple Vend shops authenticate through the same application, users from different shops with the same internal Vend user ID could collide in the social-auth association table. A user from one shop could then be authenticated as the local account previously associated with the same numeric user ID from another shop. The issue affects applications using the Vend OAuth2 backend with more than one Vend shop. Version 5.0.0 patches the issue.22dCVE-2026-571756.4 MED12.7%
——4Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the SAML backend accepted SAML responses on the Assertion Consumer Service endpoint without verifying that they matched a previously issued `AuthnRequest`. Applications using SAML account association could allow an attacker with a valid account on a trusted IdP to link the attacker's SAML identity to a logged-in victim's local account. The attacker could then authenticate through SAML and gain access to the victim's account. The issue affects applications using the SAML backend together with authenticated account association. The issue has been fixed in version 5.0.0 by validating SAML responses against stored `AuthnRequest` IDs.15dCVE-2026-544616.5 MED20.8%
——6Habitica is a habit tracker application that treats goals like a role-playing game. From 4.172.1 until 5.48.2, a query parameter on Habitica's /api/v3/groups/:groupId/members route is not sanitized before being interpreted as a regular expression. An authenticated caller can supply a computationally expensive regular expression that degrades application performance or halts Node.js processes. This issue is fixed in version 5.48.2.22dCVE-2026-97521—4.2%
——1In the Linux kernel, the following vulnerability has been resolved:
gfs2: fix quota init duplicate scan
gfs2_quota_init() checks for duplicate quota_change IDs while holding
qd_lock and the quota hash bucket bitlock. That path used
gfs2_qd_search_bucket(), which takes a lockref reference via
lockref_get_not_dead().
On PREEMPT_RT this may sleep, which is not allowed under the bucket
bitlock, triggering "sleeping function called from invalid context".
Use a no-ref bucket lookup in this path, then continue duplicate
handling without taking a lockref there.
Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper
so lookup traversal stays in one place.
This patch fixes a bug reported by syzbot.23dCVE-2026-975207.1 HIG1.8%
——1In the Linux kernel, the following vulnerability has been resolved:
gfs2: move quota_init qc iterator increment
Move qc++ from the loop body into the for-loop increment
expression in gfs2_quota_init().
This keeps iterator progression explicit and avoids mixing pointer
advance with duplicate-slot handling in the loop body.23dCVE-2026-97519—3.4%
——1In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix null pointer dereference in devcoredump cleanup
In xe_devcoredump_snapshot_free(), ss->gt may be NULL when the snapshot
was never fully populated (e.g., when cleanup is triggered without a
prior capture). Guard the xe_guc_capture_put_matched_nodes() call with
IS_ERR_OR_NULL() to prevent a null dereference.
In xe_devcoredump_free(), the deferred work is only queued when a
coredump is captured, so guard cancel_work_sync() with a check on
coredump->captured.23dCVE-2026-97518—4.2%
——1In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: reject duplicate wiphy cipher suite entries
Duplicate entries in wiphy->cipher_suites do not describe any
additional capability, but cfg80211 currently accepts them and leaves
individual consumers to deal with them.
One such consumer is the WEXT compatibility code, which appends a WEP
key length for each WEP cipher entry it sees. Repeated WEP entries can
therefore overflow the fixed iw_range::encoding_size array returned by
SIOCGIWRANGE.
Reject duplicate cipher suite entries in wiphy_register() instead.
This keeps the cipher suite invariant in one place and makes malformed
wiphy descriptions fail early with -EINVAL, rather than relying on a
single cfg80211 user to handle duplicates correctly.23dCVE-2026-97517—4.4%
——1In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: reject beacons with bad HE operation
The HE operation element not only needs to be longer than
the fixed part, but also have an appropriate size for the
variable part inside of it. Check this.18dCVE-2026-97516—4.4%
——1In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: Add NULL check for chip->edcca_th in rtw_fw_adaptivity_result()
It was recently reported that rtw_fw_adaptivity_result()
in fw.c dereferences rtwdev->chip->edcca_th without
a NULL check. The issue is that devices with the
8821CE chip don't define edcca_th in their chip
info. As a result, when rtw_fw_adaptivity_result()
tries to dereference it, the kernel triggers an oops.
Add a NULL check for edcca_th before dereferencing
it in rtw_fw_adaptivity_result() in fw.c. Placing
the check at the function entry avoids logging any
garbage values.
This change does not address the root cause for
this behavior, but it prevents the NULL dereference
and the resulting oops while a more permanent solution
is developed.
Tested on a 8822CE chip which defines edcca_th, so
this issue is not present on it, but it still uses
this driver and I can verify there are no regressions.18dCVE-2026-97515—3.4%
——1In the Linux kernel, the following vulnerability has been resolved:
i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845
On NPCM845, when a target on the I3C bus gets stuck holding SDA low,
the controller reports a false Master Request (MR) in-band interrupt
event. The driver handles this by emitting a STOP condition to restore
the bus.
However, the hardware quirk SVC_I3C_QUIRK_FALSE_SLVSTART indicates that
emitting a STOP condition may spuriously set the SLVSTART interrupt
status bit. In the Master Request case, this creates a feedback loop:
the STOP triggers a new SLVSTART event, the IRQ handler fires again,
the controller still reports an MR type, another STOP is emitted, and
the cycle repeats indefinitely, resulting in an IRQ storm that can lock
up the CPU.
Clear the SLVSTART status bit explicitly after emitting the STOP in the
Master Request IBI handler when the SVC_I3C_QUIRK_FALSE_SLVSTART quirk
is set. This breaks the feedback loop without affecting normal SLVSTART
processing, which is already guarded in the top-level IRQ handler by
checking that MSTATUS is in SLVREQ state.23dCVE-2026-97514—4.2%
——1In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Fix Reports from Kernel Lock Validator
handle_dynamic_resolution change requires that the state_lock be acquired
based on the lockdep_assert_held. However, the
handle_dynamic_resolution_change call in initialize_sequence does not
properly obtain the lock before calling.
Since the v4l2_ctrl_find and s_ctrl can sleep, they should not be called
while a lock is already held. Store off the fbc_buf_count then properly
update control once lock has been freed.23dCVE-2026-975137.8 HIG1.4%
——0In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Release m2m_ctx after Instance Removed from List
Possible use after free if IRQ thread manages to obtain spinlock between
m2m_ctx release and wave5_release function removing stream instance from
list of active instances. The IRQ thread looks for the m2m_ctx which is
freed so null pointer dereference occurs.23dCVE-2026-97512—4.4%
——1In the Linux kernel, the following vulnerability has been resolved:
spi: spi-qcom-qspi: Fix incomplete error handling in runtime PM
The runtime PM functions had incomplete error handling that could leave the
system in an inconsistent state. If any operation failed midway through
suspend or resume, some resources would be left in the wrong state while
others were already changed, leading to potential clock/power imbalances.
Reorder the suspend/resume sequences to avoid brownout risk by ensuring the
performance state is set appropriately before clocks are enabled and clocks
are disabled before dropping the performance state.
Fix by adding proper error checking for all operations and using goto-based
cleanup to ensure all successfully acquired resources are properly released
on any error.18dCVE-2026-97511—3.4%
——1In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: avoid out-of-bounds access in monitor
In NAN, we don't know on what band the frame will be sent. Therefore we
set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound
access in ieee80211_add_tx_radiotap_header when we try to access the
sbands array.
Fix it by not accessing the array if the band is NUM_NL80211_BANDS.
This means that we will not report rate info for legacy rate in NAN.
But nobody really cares about it.23dCVE-2026-97510—4.9%
——1In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Release request if tb_cfg_request() fails in __tb_xdomain_response()
If tb_cfg_request() fails setting up the request (for example the
control channel is shut down already) it returns an error without
calling the callback. To avoid leaking that memory, call
tb_cfg_request_put() if tb_cfg_request() fails.18dCVE-2026-975098.8 HIG14.0%
——4In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Keep XDomain reference during the lifetime of a service
This is needed because we release the service ID in tb_service_release()
and the ID array is owned by the parent XDomain.18dCVE-2026-975087.5 HIG12.3%
——4In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Set tb->root_switch to NULL when domain is stopped
Similarly what we do with the firmware connection manager. This makes
tb_xdp_handle_request() return error to the remote host. However, we
need to make sure we keep the uuid alive so that we can reply until the
whole domain is released.18dCVE-2026-97507—4.9%
——1In the Linux kernel, the following vulnerability has been resolved:
media: dm1105: fix missing error check for dma_alloc_coherent
The return value of dm1105_dma_map(), which handles DMA memory allocation,
is ignored in dm1105_hw_init(). If dma_alloc_coherent() fails, the driver
will proceed using a NULL pointer for DMA transfers, leading to a kernel
oops or invalid hardware access.
Fix this by checking the return value and propagating -ENOMEM on failure.18dCVE-2026-97506—4.9%
——1In the Linux kernel, the following vulnerability has been resolved:
crypto: ixp4xx - fix buffer chain unwind on allocation failure
chainup_buffers() builds a linked list of buffer descriptors for a
scatterlist. If dma_pool_alloc() fails while constructing the list, the
current code sets buf to NULL and later dereferences it unconditionally
at the end of the function:
buf->next = NULL;
buf->phys_next = 0;
This can lead to a null-pointer dereference on allocation failure.
If the failure happens after part of the descriptor chain has already
been allocated and DMA-mapped, the partially constructed chain also
needs to be released.
Fix this by terminating the partially constructed chain on allocation
failure and letting the callers unwind it via their existing cleanup
paths. Also fix ablk_perform() to preserve the hook pointers before
checking for failure, so partially built chains can be freed correctly.18dCVE-2026-97505—4.2%
——1In the Linux kernel, the following vulnerability has been resolved:
PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store()
Currently, the __resource_resize_store() allows writing to the
resourceN_resize sysfs attribute to change a BAR's size without checking
for capabilities, currently relying only on the file access check.
Resizing a BAR modifies PCI device configuration and can disrupt active
drivers. After the upcoming conversion to static attributes, it will also
trigger resource file updates via sysfs_update_groups().
Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR
resize operations.23dCVE-2026-97504—4.2%
——1In the Linux kernel, the following vulnerability has been resolved:
watchdog: lenovo_se10_wdt: Fix use-after-free and resource leak risk
Review by sashiko.dev highlighted potential use after free and resource
leak instances.
Set se10_pdev to null to prevent use after free
Remove DMI call back and instead directly call
se10_create_platform_device. Handle error cases appropriately23dCVE-2026-97503—3.4%
——1In the Linux kernel, the following vulnerability has been resolved:
genirq/proc: Size interrupt directory names for 10-digit interrupt numbers
/proc/irq/<n>/ directory names are built in `char name[10]` buffers
with `sprintf(name, "%u", irq)`.
Ten-digit IRQ numbers already need 11 bytes including the trailing NUL, and
current sparse-IRQ configurations allow interrupt numbers in that range.
Size the temporary name buffer for the current decimal form and switch
to bounded formatting when creating or removing the proc entry.23dCVE-2026-97502—4.9%
——1In the Linux kernel, the following vulnerability has been resolved:
mmc: davinci: avoid NULL deref of host->data in IRQ handler
mmc_davinci_irq() returns early only when both host->cmd and
host->data are NULL:
if (host->cmd == NULL && host->data == NULL) {
...
return IRQ_NONE;
}
So we may legitimately reach the rest of the handler with
host->data == NULL (and therefore data == NULL). The DATDNE branch
already guards against this with an explicit "if (data != NULL)"
check, but the subsequent TOUTRD ("read data timeout") and
CRCWR/CRCRD ("data CRC error") branches dereference data
unconditionally:
if (qstatus & MMCST0_TOUTRD) {
data->error = -ETIMEDOUT; <-- NULL deref
...
davinci_abort_data(host, data);
}
if (qstatus & (MMCST0_CRCWR | MMCST0_CRCRD)) {
data->error = -EILSEQ; <-- NULL deref
...
}
If either bit is set in qstatus while host->data is NULL, the kernel
will crash inside the IRQ handler. smatch flags this:
drivers/mmc/host/davinci_mmc.c:933 mmc_davinci_irq() error: we
previously assumed 'data' could be null (see line 914)
Gate both branches on a non-NULL data, matching the existing pattern
used by the DATDNE branch.
No functional change for callers where data is non-NULL, which is
the only case in which these branches did meaningful work before
this change.18dCVE-2026-97501—4.1%
——1In the Linux kernel, the following vulnerability has been resolved:
pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction
pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take
the pinctrl mutex. This causes a gpiochip operations to need to sleep.
Worse yet, the .can_sleep field in the gpiochip is not set. This causes
the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check
whether it can use a spinlock or needs a mutex. In this case, it ends
up taking a spinlock, then calls pinctrl_gpio_direction_output(), which
takes a mutex. This causes a huge warning.
While this class of Mediatek hardware does not have separate clear/set
registers, the pinctrl context has a spinlock that is taken whenever
a register read-modify-write is done. Also, once the GPIO function is
selected / muxed in, further GPIO operations do not involve pinctrl
operations or state. The GPIO direction and level values do not require
toggling the pinmux or any other pin config options.
Switch to directly calling mtk_pinmux_gpio_set_direction() in the GPIO
set direction callbacks to avoid taking the pinctrl mutex. Drop the
.gpio_set_direction field in mtk_pmxops to signal we are no longer using
the pinctrl GPIO layer for setting the direction.23dCVE-2026-97500—4.4%
——1In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: phy: check length before parsing PHY status IE
Hardware might report PHY status IE with unexpected length, and parser
might access out of range. Check the length ahead.18dCVE-2026-97499—4.3%
——1In the Linux kernel, the following vulnerability has been resolved:
coresight: perf: Retrieve path and source from event data
ETM perf callbacks currently use the per-CPU csdev_src pointer, which
can race with updates during device registration and unregistration.
The AUX setup already builds and stores the path in the event data.
Use this path to retrieve the source instead of csdev_src to avoid
the race.
Export coresight_get_source() and add etm_event_get_ctxt_path() to
retrieve the context's path and its source with READ_ONCE() /
WRITE_ONCE() accessors. Give the comments to explain why this
approach is safe when pause or resume callbacks preempt the disable
callback (e.g. via NMI).23dCVE-2026-97498—4.3%
——1In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction
mqd and fw objects are queue core objects which should remain
valid and never be unmapped and evicted for user queues to work
properly.
During eviction if these buffers are evicted the hw continue to
use the invalid addresses and caused page faults and system hung.23dCVE-2026-974977.8 HIG2.2%
——1In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds for allocate_sdma_queue restore_sdma_id
allocate_sdma_queue has an option where the sdma queue id can be
specified (used by CRIU). We weren't bounds-checking that
value.
Confirm it's less than the maximum number of queues.18dCVE-2026-974967.1 HIG2.0%
——1In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix OOB memory exposure in get_wave_state()
The get_wave_state() function for v9 trusts cp_hqd_cntl_stack_size and
cp_hqd_cntl_stack_offset values read directly from the MQD, which are
written by GPU microcode and fully attacker-controlled on the
CRIU-restore path (via AMDKFD_IOC_RESTORE_PROCESS with H3).
this leads to an unbounded copy_to_user() that can leak adjacent
GTT/kernel memory. If offset > size, integer underflow produces a ~4 GiB
read length, if size is set to 1 MiB against a 4 KiB allocation, we leak
1 MiB of adjacent kernel memory (other queues' MQDs, ring buffers, KASLR
pointers).
Fix by clamping both cp_hqd_cntl_stack_size to the actual allocated
buffer size (q->ctl_stack_size) and cp_hqd_cntl_stack_offset to the
clamped size before performing arithmetic and copy_to_user().
This ensures we never read beyond the allocated kernel BO regardless of
attacker-supplied MQD field values.18dCVE-2026-97495—5.7%
——2In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds on allocate_doorbell
allocated_doorbell has an option to set the doorbell id
to a specific value (used by CRIU). This value was not
bounds checked.
Check to confirm it's less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS.18dCVE-2026-97494—5.5%
——2In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: validate and share PSP fw_pri_buf copies via psp_copy_fw
Change psp_copy_fw from void to int: return -ENODEV when drm_dev_enter
fails, and -EINVAL when the image size is zero or larger than the
1 MiB PSP private buffer.
Replace open-coded memset/memcpy into fw_pri_buf with psp_copy_fw.23dCVE-2026-97493—4.3%
——1In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Bound GPIO I2C table entry count from VBIOS
Reject undersized tables and cap the derived entry count
to AMDGPU_MAX_I2C_BUS so we do not overrun adev->i2c_bus[]
or walk an absurd number of entries on corrupt size fields.23dCVE-2026-97492—6.3%
——2In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed
In case reconfiguration of NAN fails, we call
ieee80211_handle_reconfig_failure, that marks all interfaces as not in
the driver.
Then, at the error path of the reconfig, cfg80211_shutdown_all_interfaces
is called to destroy all the interfaces.
If we have any other interface but the NAN one, for example a BSS
station, then when its state (links, stations) will be removed, we
won't tell the driver about this, because we will think that the
interfaces are not in the driver, and then drivers might remain with
dangling pointers to objects like stations and links (at least for
iwlwifi this is the case).
ieee80211_handle_reconfig_failure is meant to be called after we cleaned
up the state in the driver, there is no reason to call it for NAN
reconfiguration failure.
Fix the code to just warn in such a case, as we do in other error paths
in reconfig where it is too complicated to rewind.18dCVE-2026-97491—6.3%
——2In the Linux kernel, the following vulnerability has been resolved:
net/rds: Don't sleep inside rds_ib_conn_path_shutdown
New rds rdma self tests exposed a hang when tearing down
the ib network configs. This is caused by the shutdown worker
thread sleeping on the wait_event call, which blocks other work
items in the queue. Fix this by changing wait_event to
wait_event timeout, and looping until the wait check succeeds.18dCVE-2026-97490—6.3%
——2In the Linux kernel, the following vulnerability has been resolved:
affs: handle set_blocksize failures
affs uses buffer_heads, which don't handle block size > PAGE_SIZE well.
Without this, mounting we will hit the
