Linux Distros Unpatched Vulnerability : CVE-2026-45884

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - apparmor: avoid per-cpu hold underflow in aagetbuffer When aagetbuffer pulls from the per-cpu list it unconditionally decrements cache-hold. If hold reaches 0...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

CVE-2026-6957 Path traversal in Mattermost Legal Hold plugin via unsanitized file name from federated peer allows arbitrary file write.

Mattermost Plugins versions =1.1.5 fail to sanitize filenames received from federated peers before using them to construct export destination paths, which allows an administrator of a remote federated Mattermost server to write files to arbitrary locations within the target server's filestore via...

CVE-2026-6957

Mattermost Plugin versions ≤ 1.1.5 are affected by a path traversal vulnerability in the export path construction from unsanitized filenames received from federated peers. An attacker — specifically an administrator of a remote federated Mattermost server — can cause files to be written to arbitr...

UBUNTU-CVE-2026-45884

In the Linux kernel, the following vulnerability has been resolved: apparmor: avoid per-cpu hold underflow in aagetbuffer When aagetbuffer pulls from the per-cpu list it unconditionally decrements cache-hold. If hold reaches 0 while count is still non-zero, the unsigned decrement wraps to UINTMAX...

CVE-2026-45884

The CVE-2026-45884 issue affects the Linux kernel’s AppArmor path, where aa_get_buffer() decrements cache->hold when pulling from the per-CPU list. If hold hits 0 while count is non-zero, the unsigned decrement can wrap to UINT_MAX, keeping hold non-zero and preventing aa_put_buffer() from ret...
