| Memory corruption while releasing shared resources in MinkSocket listener thread. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Avoid unnecessary destruction of file_ida
file_ida is allocated during cdev open and is freed accordingly
during cdev release. This sequence is guaranteed by driver file
operations. Therefore, there is no need to destroy an already empty
file_ida when the WQ cdev is removed.
Worse, ida_free() in cdev release may happen after destruction of
file_ida per WQ cdev. This can lead to accessing an id in file_ida
after it has been destroyed, resulting in a kernel panic.
Remove ida_destroy(&file_ida) to address these issues. |
| OpenSynergy BlueSDK (aka Blue SDK) through 6.x has a Use-After-Free. The specific flaw exists within the BlueSDK Bluetooth stack. The issue results from the lack of validating the existence of an object before performing operations on the object (aka use after free). An attacker can leverage this to achieve remote code execution in the context of a user account under which the Bluetooth process runs. |
| Use after free in Windows Bluetooth Service allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Hyper-V allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Management Services allows an unauthorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Brokering File System allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Connected Devices Platform Service allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Win32K - GRFX allows an authorized attacker to execute code locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows UI XAML Maps MapControlSettings allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows BitLocker allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Capability Access Management Service (camsvc) allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/migrate_device: don't add folio to be freed to LRU in migrate_device_finalize()
If migration succeeded, we called
folio_migrate_flags()->mem_cgroup_migrate() to migrate the memcg from the
old to the new folio. This will set memcg_data of the old folio to 0.
Similarly, if migration failed, memcg_data of the dst folio is left unset.
If we call folio_putback_lru() on such folios (memcg_data == 0), we will
add the folio to be freed to the LRU, making memcg code unhappy. Running
the hmm selftests:
# ./hmm-tests
...
# RUN hmm.hmm_device_private.migrate ...

Likely, nothing else goes wrong: putting the last folio reference will
remove the folio from the LRU again. So besides memcg complaining, adding
the folio to be freed to the LRU is just an unnecessary step.
The new flow resembles what we have in migrate_folio_move(): add the dst
to the lru, rem

| In the Linux kernel, the following vulnerability has been resolved:
ASoC: topology: Fix references to freed memory
Most users after parsing a topology file, release memory used by it, so
having pointer references directly into topology file contents is wrong.
Use devm_kmemdup(), to allocate memory as needed. |
| A use-after-free issue was addressed with improved memory management. This issue is fixed in watchOS 11.5, macOS Sonoma 14.7.6, tvOS 18.5, iPadOS 17.7.7, iOS 18.5 and iPadOS 18.5, macOS Sequoia 15.5, visionOS 2.5, macOS Ventura 13.7.6. Parsing a file may lead to an unexpected app termination. |
| Use after free in some Zoom Workplace Apps and SDKs may allow an authenticated user to conduct a denial of service via network access. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix slab-use-after-free on hdcp_work
[Why]
A slab-use-after-free is reported when HDCP is destroyed but the
property_validate_dwork queue is still running.
[How]
Cancel the delayed work when destroying workqueue.

| In the Linux kernel, the following vulnerability has been resolved:
drm/dp_mst: Ensure mst_primary pointer is valid in drm_dp_mst_handle_up_req()
While receiving an MST up request message from one thread in
drm_dp_mst_handle_up_req(), the MST topology could be removed from
another thread via drm_dp_mst_topology_mgr_set_mst(false), freeing
mst_primary and setting drm_dp_mst_topology_mgr::mst_primary to NULL.
This could lead to a NULL deref/use-after-free of mst_primary in
drm_dp_mst_handle_up_req().
Avoid the above by holding a reference for mst_primary in
drm_dp_mst_handle_up_req() while it's used.
v2: Fix kfreeing the request if getting an mst_primary reference fails. |
| In the Linux kernel, the following vulnerability has been resolved:
hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer
When hvs is released, there is a possibility that vsk->trans may not
be initialized to NULL, which could lead to a dangling pointer.
This issue is resolved by initializing vsk->trans to NULL. |
