| In the Linux kernel, the following vulnerability has been resolved:
tee: fix register_shm_helper()
In register_shm_helper(), fix incorrect error handling for a call to
iov_iter_extract_pages(). A case is missing for when
iov_iter_extract_pages() only got some pages and return a number larger
than 0, but not the requested amount.
This fixes a possible NULL pointer dereference following a bad input from
ioctl(TEE_IOC_SHM_REGISTER) where parts of the buffer isn't mapped. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: check the return value of pinmux_ops::get_function_name()
While the API contract in docs doesn't specify it explicitly, the
generic implementation of the get_function_name() callback from struct
pinmux_ops - pinmux_generic_get_function_name() - can fail and return
NULL. This is already checked in pinmux_check_ops() so add a similar
check in pinmux_func_name_to_selector() instead of passing the returned
pointer right down to strcmp() where the NULL can get dereferenced. This
is normal operation when adding new pinfunctions. |
| A vulnerability was found in RefindPlusRepo RefindPlus 0.14.2.AB. It has been classified as problematic. This affects the function InternalApfsTranslateBlock of the file Library/RP_ApfsLib/RP_ApfsIo.c. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The patch is named 4d35125ca689a255647e9033dd60c257d26df7cb. It is recommended to apply a patch to fix this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: Check return value of platform_get_resource()
platform_get_resource() returns NULL in case of failure, so check its
return value and propagate the error in order to prevent NULL pointer
dereference. |
| A vulnerability was found in RefindPlusRepo RefindPlus 0.14.2.AB and classified as problematic. Affected by this issue is the function GetDebugLogFile of the file Library/MemLogLib/BootLog.c. The manipulation leads to null pointer dereference. Attacking locally is a requirement. The patch is identified as d2143a1e2deefddd9b105fb7160763c4f8d47ea2. It is recommended to apply a patch to fix this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: essiv - Check ssize for decryption and in-place encryption
Move the ssize check to the start in essiv_aead_crypt so that
it's also checked for decryption and in-place encryption. |
| In the Linux kernel, the following vulnerability has been resolved:
media: iris: Fix memory leak by freeing untracked persist buffer
One internal buffer which is allocated only once per session was not
being freed during session close because it was not being tracked as
part of internal buffer list which resulted in a memory leak.
Add the necessary logic to explicitly free the untracked internal buffer
during session close to ensure all allocated memory is released
properly. |
| In the Linux kernel, the following vulnerability has been resolved:
media: stm32-csi: Fix dereference before NULL check
In 'stm32_csi_start', 'csidev->s_subdev' is dereferenced directly while
assigning a value to the 'src_pad'. However the same value is being
checked against NULL at a later point of time indicating that there
are chances that the value can be NULL.
Move the dereference after the NULL check. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: qcom: audioreach: fix potential null pointer dereference
It is possible that the topology parsing function
audioreach_widget_load_module_common() could return NULL or an error
pointer. Add missing NULL check so that we do not dereference it. |
| A vulnerability has been found in scipopt scip up to 9.2.1 and classified as problematic. Affected by this vulnerability is the function main of the file examples/LOP/src/genRandomLOPInstance.c of the component File Descriptor Handler. The manipulation of the argument File leads to uncontrolled file descriptor consumption. Local access is required to approach this attack. Upgrading to version 9.2.2 is able to address this issue. The identifier of the patch is d6da63b941216d75fbc1aefea9abf1de6712a2d0. It is recommended to upgrade the affected component. |
| In the Linux kernel, the following vulnerability has been resolved:
net/9p: Fix buffer overflow in USB transport layer
A buffer overflow vulnerability exists in the USB 9pfs transport layer
where inconsistent size validation between packet header parsing and
actual data copying allows a malicious USB host to overflow heap buffers.
The issue occurs because:
- usb9pfs_rx_header() validates only the declared size in packet header
- usb9pfs_rx_complete() uses req->actual (actual received bytes) for
memcpy
This allows an attacker to craft packets with small declared size
(bypassing validation) but large actual payload (triggering overflow
in memcpy).
Add validation in usb9pfs_rx_complete() to ensure req->actual does not
exceed the buffer capacity before copying data. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Fix use-after-free in tb_dp_dprx_work
The original code relies on cancel_delayed_work() in tb_dp_dprx_stop(),
which does not ensure that the delayed work item tunnel->dprx_work has
fully completed if it was already running. This leads to use-after-free
scenarios where tb_tunnel is deallocated by tb_tunnel_put(), while
tunnel->dprx_work remains active and attempts to dereference tb_tunnel
in tb_dp_dprx_work().
A typical race condition is illustrated below:
CPU 0 | CPU 1
tb_dp_tunnel_active() |
tb_deactivate_and_free_tunnel()| tb_dp_dprx_start()
tb_tunnel_deactivate() | queue_delayed_work()
tb_dp_activate() |
tb_dp_dprx_stop() | tb_dp_dprx_work() //delayed worker
cancel_delayed_work() |
tb_tunnel_put(tunnel); |
| tunnel = container_of(...); //UAF
| tunnel-> //UAF
Replacing cancel_delayed_work() with cancel_delayed_work_sync() is
not feasible as it would introduce a deadlock: both tb_dp_dprx_work()
and the cleanup path acquire tb->lock, and cancel_delayed_work_sync()
would wait indefinitely for the work item that cannot proceed.
Instead, implement proper reference counting:
- If cancel_delayed_work() returns true (work is pending), we release
the reference in the stop function.
- If it returns false (work is executing or already completed), the
reference is released in delayed work function itself.
This ensures the tb_tunnel remains valid during work item execution
while preventing memory leaks.
This bug was found by static analysis. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: mvsas: Fix use-after-free bugs in mvs_work_queue
During the detaching of Marvell's SAS/SATA controller, the original code
calls cancel_delayed_work() in mvs_free() to cancel the delayed work
item mwq->work_q. However, if mwq->work_q is already running, the
cancel_delayed_work() may fail to cancel it. This can lead to
use-after-free scenarios where mvs_free() frees the mvs_info while
mvs_work_queue() is still executing and attempts to access the
already-freed mvs_info.
A typical race condition is illustrated below:
CPU 0 (remove) | CPU 1 (delayed work callback)
mvs_pci_remove() |
mvs_free() | mvs_work_queue()
cancel_delayed_work() |
kfree(mvi) |
| mvi-> // UAF
Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
that the delayed work item is properly canceled and any executing
delayed work item completes before the mvs_info is deallocated.

| In the Linux kernel, the following vulnerability has been resolved:
blk-mq: fix blk_mq_tags double free while nr_requests grown
In the case user trigger tags grow by queue sysfs attribute nr_requests,
hctx->sched_tags will be freed directly and replaced with a new
allocated tags, see blk_mq_tag_update_depth().
The problem is that hctx->sched_tags is from elevator->et->tags, while
et->tags is still the freed tags, hence later elevator exit will try to
free the tags again, causing kernel panic.
Fix this problem by replacing et->tags with new allocated tags as well.
Noted there are still some long term problems that will require some
refactor to be fixed thoroughly[1].

| In the Linux kernel, the following vulnerability has been resolved:
mm: swap: check for stable address space before operating on the VMA
It is possible to hit a zero entry while traversing the vmas in unuse_mm()
called from swapoff path and accessing it causes the OOPS:
Unable to handle kernel NULL pointer dereference at virtual address
0000000000000446--> Loading the memory from offset 0x40 on the
XA_ZERO_ENTRY as address.
Mem abort info:
ESR = 0x0000000096000005
EC = 0x25: DABT (current EL), IL = 32 bits
SET = 0, FnV = 0
EA = 0, S1PTW = 0
FSC = 0x05: level 1 translation fault
The issue is manifested from the below race between the fork() on a
process and swapoff:
fork(dup_mmap()) swapoff(unuse_mm)
--------------- -----------------
1) Identical mtree is built using
__mt_dup().
2) copy_pte_range()-->
copy_nonpresent_pte():
The dst mm is added into the
mmlist to be visible to the
swapoff operation.
3) Fatal signal is sent to the parent
process(which is the current during the
fork) thus skip the duplication of the
vmas and mark the vma range with
XA_ZERO_ENTRY as a marker for this process
that helps during exit_mmap().
4) swapoff is tried on the
'mm' added to the 'mmlist' as
part of the 2.
5) unuse_mm(), that iterates
through the vma's of this 'mm'
will hit the non-NULL zero entry
and operating on this zero entry
as a vma is resulting into the
oops.
The proper fix would be around not exposing this partially-valid tree to
others when droping the mmap lock, which is being solved with [1]. A
simpler solution would be checking for MMF_UNSTABLE, as it is set if
mm_struct is not fully initialized in dup_mmap().
Thanks to Liam/Lorenzo/David for all the suggestions in fixing this
issue. |

wifi: ath11k: fix NULL dereference in ath11k_qmi_m3_load()
If ab->fw.m3_data points to data, then fw pointer remains null.
Further, if m3_mem is not allocated, then fw is dereferenced to be
passed to ath11k_err function.
Replace fw->size by m3_len.
