| Issue summary: When CMS password-based decryption (RFC 3211 / PWRI key unwrap)
processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK
cipher can trigger a heap out-of-bounds read in kek_unwrap_key().
Impact summary: A heap buffer over-read may trigger a crash which leads to
Denial of Service for an application if the input buffer ends at a memory
page boundary and the following page is unmapped. There is no information
disclosure as the over-read bytes are not revealed to the attacker.
The key unwrapping function performs a check-byte test as specified in the
RFC that reads 7 bytes from a heap allocation that is based on the wrapped
key length from the message. There is a minimum length check based on the
block length of the wrapping cipher. However the cipher is selected from
an OID carried in the attacker's PWRI keyEncryptionAlgorithm with no
requirement that the cipher be a block cipher. When an attacker selects
a stream-mode cipher the guard will be ineffective and the allocated buffer
containing the unwrapped key can be too small to fit the check-bytes
specified in the RFC and a buffer over-read can happen.
Applications calling CMS_decrypt() or CMS_decrypt_set1_password()
(equivalently openssl cms -decrypt -pwri_password ...) on untrusted CMS
data are vulnerable to this issue. No password knowledge is required: the
over-read happens during the unwrap attempt before any authentication
succeeds.
The over-read is limited to a few bytes and is not written to output, so
there is no information disclosure. Triggering a crash requires the
allocation to border unmapped memory, which is unlikely with the normal
allocator.
The FIPS modules are not affected by this issue. |

apparmor: fix invalid deref of rawdata when export_binary is unset
If the export_binary parameter is disabled on runtime, profiles that
were loaded before that will still have their rawdata stored in
apparmorfs, with a symbolic link to the rawdata on the policy
directory. When one of those profiles are replaced, the rawdata is set
to NULL, but when trying to resolve the symbolic links to rawdata for
that profile, it will try to dereference profile->rawdata->name when
profile->rawdata is now NULL causing an oops. Fix it by checking if
rawdata is set.

| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix NULL pointer dereference in __unix_needs_revalidation
When receiving file descriptors via SCM_RIGHTS, both the socket pointer
and the socket's sk pointer can be NULL during socket setup or teardown,
causing NULL pointer dereferences in __unix_needs_revalidation().
This is a regression in AppArmor 5.0.0 (kernel 6.17+) where the new
__unix_needs_revalidation() function was added without proper NULL checks.
The crash manifests as:
BUG: kernel NULL pointer dereference, address: 0x0000000000000018

The function dereferences sock->sk->sk_family without checking if either
sock or sock->sk is NULL first.
Add NULL checks for both sock and sock->sk before accessing sk_family. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Return proper address for non-zero offsets in insn array
The map_direct_value_addr() function of the instruction
array map incorrectly adds offset to the resulting address.
This is a bug, because later the resolve_pseudo_ldimm64()
function adds the offset. Fix it. Corresponding selftests
are added in a consequent commit. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: playstation: Add missing check for input_ff_create_memless
The ps_gamepad_create() function calls input_ff_create_memless()
without verifying its return value, which can lead to incorrect
behavior or potential crashes when FF effects are triggered.
Add a check for the return value of input_ff_create_memless(). |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Limit bpf program signature size
Practical BPF signatures are significantly smaller than
KMALLOC_MAX_CACHE_SIZE
Allowing larger sizes opens the door for abuse by passing excessive
size values and forcing the kernel into expensive allocation paths (via
kmalloc_large or vmalloc). |
| In the Linux kernel, the following vulnerability has been resolved:
ublk: use READ_ONCE() to read struct ublksrv_ctrl_cmd
struct ublksrv_ctrl_cmd is part of the io_uring_sqe, which may lie in
userspace-mapped memory. It's racy to access its fields with normal
loads, as userspace may write to them concurrently. Use READ_ONCE() to
copy the ublksrv_ctrl_cmd from the io_uring_sqe to the stack. Use the
local copy in place of the one in the io_uring_sqe. |
| In the Linux kernel, the following vulnerability has been resolved:
fbnic: close fw_log race between users and teardown
Fixes a theoretical race on fw_log between the teardown path and fw_log
write functions.
fw_log is written inside fbnic_fw_log_write() and can be reached from
the mailbox handler fbnic_fw_msix_intr(), but fw_log is freed before
IRQ/MBX teardown during cleanup, resulting in a potential data race of
dereferencing a freed/null variable.
Possible Interleaving Scenario:
CPU0: fbnic_fw_msix_intr() // Entry
fbnic_fw_log_write()
if (fbnic_fw_log_ready()) // true
... preempt ...
CPU1: fbnic_remove() // Entry
fbnic_fw_log_free()
vfree(log->data_start);
log->data_start = NULL;
CPU0: continues, walks log->entries or writes to log->data_start
The initialization also has an incorrect order problem, as the fw_log
is currently allocated after MBX setup during initialization.
Fix the problems by adjusting the synchronization order to put
initialization in place before the mailbox is enabled, and not cleared
until after the mailbox has been disabled. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: greybus: lights: avoid NULL deref
gb_lights_light_config() stores channel_count before allocating the
channels array. If kcalloc() fails, gb_lights_release() iterates the
non-zero count and dereferences light->channels, which is NULL.
Allocate channels first and only then publish channels_count so the
cleanup path can't walk a NULL pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Stop job scheduling across aie2_release_resource()
Running jobs on a hardware context while it is in the process of
releasing resources can lead to use-after-free and crashes.
Fix this by stopping job scheduling before calling
aie2_release_resource() and restarting it after the release completes.
Additionally, aie2_sched_job_run() now checks whether the hardware
context is still active. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: ab8500: Fix use-after-free in power_supply_changed()
Using the `devm_` variant for requesting IRQ _before_ the `devm_`
variant for allocating/registering the `power_supply` handle, means that
the `power_supply` handle will be deallocated/unregistered _before_ the
interrupt handler (since `devm_` naturally deallocates in reverse
allocation order). This means that during removal, there is a race
condition where an interrupt can fire just _after_ the `power_supply`
handle has been freed, *but* just _before_ the corresponding
unregistration of the IRQ handler has run.
This will lead to the IRQ handler calling `power_supply_changed()` with
a freed `power_supply` handle. Which usually crashes the system or
otherwise silently corrupts the memory...
Note that there is a similar situation which can also happen during
`probe()`; the possibility of an interrupt firing _before_ registering
the `power_supply` handle. This would then lead to the nasty situation
of using the `power_supply` handle *uninitialized* in
`power_supply_changed()`.
Commit 1c1f13a006ed ("power: supply: ab8500: Move to componentized
binding") introduced this issue during a refactorization. Fix this racy
use-after-free by making sure the IRQ is requested _after_ the
registration of the `power_supply` handle. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Fix memory leak in starfive_aes_aead_do_one_req()
The starfive_aes_aead_do_one_req() function allocates rctx->adata with
kzalloc() but fails to free it if sg_copy_to_buffer() or
starfive_aes_hw_init() fails, which lead to memory leaks.
Since rctx->adata is unconditionally freed after the write_adata
operations, ensure consistent cleanup by freeing the allocation in these
earlier error paths as well.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: au1200fb: Fix a memory leak in au1200fb_drv_probe()
In au1200fb_drv_probe(), when platform_get_irq fails(), it directly
returns from the function with an error code, which causes a memory
leak.
Replace it with a goto label to ensure proper cleanup. |
| In the Linux kernel, the following vulnerability has been resolved:
ublk: Validate SQE128 flag before accessing the cmd
ublk_ctrl_cmd_dump() accesses (header *)sqe->cmd before
IO_URING_F_SQE128 flag check. This could cause out of boundary memory
access.
Move the SQE128 flag check earlier in ublk_ctrl_uring_cmd() to return
-EINVAL immediately if the flag is not set. |
