| In the Linux kernel, the following vulnerability has been resolved:
phonet: pep: fix use-after-free in pep_get_sb()
pep_get_sb() doesn't consider that pskb_may_pull() might have relocated
the skb data, and continue to access the older pointer, causing UAF.
Reproduced under KASAN:
BUG: KASAN: slab-use-after-free in pep_get_sb+0x234/0x3b0

Refetch the header with skb_header_pointer() after pskb_may_pull(), so
the possibly stale pointer is no longer dereferenced. There are better
ways to solve this, but, this is the less instrusive one. |
| In the Linux kernel, the following vulnerability has been resolved:
iomap: fix out-of-bounds bitmap_set() with zero-length range
ifs_set_range_dirty() and ifs_set_range_uptodate() compute last_blk
as (off + len - 1) >> i_blkbits. When off is 0 and len is 0, the
unsigned subtraction underflows to SIZE_MAX, producing a huge
last_blk and nr_blks value that causes bitmap_set() to write far
beyond the ifs->state allocation.
Regarding ifs_set_range_uptodate(), it is temporarily safe because len
cannot be passed in as 0. However, for ifs_set_range_dirty() this is
reachable from __iomap_write_end(): when copy_folio_from_iter_atomic()
returns 0 (e.g. user buffer fault) and the folio is already uptodate,
the guard at the top of __iomap_write_end() does not trigger because
!folio_test_uptodate() is false, and iomap_set_range_dirty() is called
with copied == 0.
Add a !len guard to both functions before the computation, so that a
zero-length range is a no-op. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: Reject monmaps advertising zero monitors
A message of type CEPH_MSG_MON_MAP contains a monmap that is sent from a
monitor to the client. This monmap contains information about the
existing monitors in the cluster. Currently, a monmap indicating that
there are zero monitors in the cluster is treated as valid. However, it
is impossible to have zero monitors in the cluster and still receive a
valid monmap from a monitor. Therefore, such a monmap must be corrupted
and should be treated as invalid. Furthermore, a monmap with a monitor
count of zero can subsequently crash the client when attempting to open
a session with a monitor in __open_session(). This happens because the
"BUG_ON(monc->monmap->num_mon < 1)" assertion in pick_new_mon() is
triggered.
This patch extends a check in ceph_monmap_decode() to also reject
arriving mon_maps with num_mon == 0 rather than only with
num_mon > CEPH_MAX_MON.

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Protect UUID list traversal
The hci_sync conversion moved class-of-device and EIR generation from an
HCI request built under hdev->lock to asynchronous command sync work.
The worker holds hdev->req_lock, but that lock does not serialize access
to hdev->uuids against add_uuid() and remove_uuid(), which update the
list under hdev->lock.
The following interleaving can therefore occur:
CPU0 (command sync work) CPU1 (management socket)
fetch uuid from the list
list_del(&uuid->list)
kfree(uuid)
read uuid->size
KASAN reports the resulting use-after-free:

Hold hdev->lock while generating and committing the class-of-device and
EIR snapshots. Release it before sending an HCI command, so controller
waits do not happen under the device lock. This protects all UUID list
walks in these paths and restores the serialization lost in the command
sync conversion. |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gpusvm: publish dpagemap early to avoid device mapping leak on error
drm_gpusvm_get_pages() only stored the local dpagemap into
svm_pages->dpagemap on the success path. If a later page failed (e.g.
-EOPNOTSUPP when ctx->allow_mixed is false) and jumped to err_unmap,
svm_pages->dpagemap was still NULL, so __drm_gpusvm_unmap_pages() skipped
device_unmap() and leaked the device mappings already created.
Assign svm_pages->dpagemap when the first device page is mapped so the
err_unmap path can device_unmap() those mappings.
This issue was found by Sashiko AI review. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: detect_link_and_local_sink: DP alt mode timeout path leaks prev_sink reference
prev_sink is unconditionally retained via dc_sink_retain at function
entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT
returns false without releasing prev_sink. All other return paths in the
function correctly call dc_sink_release(prev_sink), making this the only
missing cleanup.

| In the Linux kernel, the following vulnerability has been resolved:
drm/imagination: fix error checking of pvr_vm_context_lookup()
Since pvr_vm_context_lookup() returns either NULL or a pointer, then stop
using IS_ERR() for checking the return value.
Using IS_ERR() leads to the kernel oops reported below. It can be
reproduced by passing an invalid VM context handle from userspace to the
DRM_IOCTL_PVR_CREATE_CONTEXT ioctl.

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix context pstate override handling
There are several problems in the context pstate handling code.
The most serious ones are potential use-after-free and NULL pointer
dereferences at context initialization time. Both are due
amdgpu_ctx_init() not holding the adev->pm.stable_pstate_ctx_lock, which
is otherwise used from both sysfs and the context code itself for
modifying and clearing the stored context pointer.
Second issue is that context fini can trample over the pstate
configuration set via sysfs. This is due the restore state
(ctx->stable_pstate) being saved at context init time, and not if, or when
the context actually changes the pstate. As the context exits it will
therefore incorrectly restore to what was set before the sysfs override
was requested.
The simplest fix is to drastically simplify how the state is tracked, by
clearly defining the points at which pstate ownership is taken and
released, and to handle all transitions under the correct lock.
Instead of at context init time, the previous state is saved only at the
point the context overrides the current state, and is restored on context
exit only if the context is still the owner of the current override state.

| Cachet through 2.4.1 contains a server-side template injection vulnerability in incident template rendering that allows authenticated users to execute arbitrary PHP code. Attackers can create malicious incident templates with Blade directives or Twig filters that execute system commands when incidents are created, achieving remote code execution as the web server process. |
| The WP Directory Kit WordPress plugin before 1.5.5 does not perform authorization or nonce checks on one of its authenticated AJAX actions, allowing any authenticated user such as a Subscriber to disclose the WP Directory Kit WordPress plugin before 1.5.5 settings including sensitive API keys and secrets. |
| Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy allows an authenticated user to execute arbitrary commands on a local or SSH-connected target server because registry.testRegistry and registry.testRegistryById in apps/dokploy/server/api/routers/registry.ts interpolate the password field into an execAsyncRemote shell command instead of using safeDockerLoginCommand. This issue is fixed in version 0.29.13. |
| The WP Directory Kit WordPress plugin before 1.5.5 does not perform authorization or nonce checks on one of its authenticated AJAX actions, allowing any authenticated user such as a Subscriber to disclose the site's user list and unpublished listings belonging to other users. |
| The GeoDirectory WordPress plugin before 2.8.169 does not perform any authorization check when returning map marker data for a single requested listing, allowing unauthenticated users to disclose the title and exact geographic coordinates of non-public (pending or draft) listings. |
| Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy allows an authenticated low-privilege member to execute arbitrary commands on the control-plane host because the volumeName field accepted by volumeBackup.create and volumeBackup.runManually is interpolated without quoting in packages/server/src/utils/volume-backups/backup.ts and executed through child_process.exec, with Docker socket access making execution host/root-equivalent. This issue is fixed in version 0.29.13. |
| The WP Data Access WordPress plugin before 5.5.79 does not validate the column names it accepts on one of its unauthenticated AJAX actions, and the nonce guarding that action does not cover them, allowing unauthenticated attackers to read arbitrary columns of the database table the affected front-end form is bound to, including user password hashes where that table is the users table. |
| TBEA TLogger V2.1.0.0B0.0.0.0 contains multiple unauthenticated denial-of-service vulnerabilities in its web server. An unauthenticated remote attacker can invoke specific HTTP endpoints to reboot or reset the device, clear application data, or terminate the web server through a segmentation fault. In addition, multiple action endpoints process attacker-controlled parameters using unsafe string operations such as sprintf() and strcat() without adequate bounds checking, allowing crafted input to trigger buffer overflows and crash the web server. The affected endpoints include onRestart, onReset, ClearData, uploadInvFile, getIndiaRPData, YearCaparity, TotalfaultData, recordData, InvHistoryData, CollectHistoryData, InvFaultData, GetPortTableByParm, and UpdatePortConfig. |
