CVE-2026-53341 fhandle: fix UAF due to unlocked ->mnt_ns read in may_decode_fh()

In the Linux kernel, the following vulnerability has been resolved: fhandle: fix UAF due to unlocked -mntns read in maydecodefh maydecodefh accesses mount::mntns without holding any locks; that means the mount can concurrently be unmounted, and the mntnamespace can concurrently be freed after an...

CVE-2026-53341

The CVE-2026-53341 issue affects the Linux kernel and is resolved by addressing a use-after-free (UAF) in may_decode_fh() where mount::mnt_ns was accessed without locks, risking a concurrent unmount/free of the mnt_namespace during an RCU grace period. The patch adds an rcu_read_lock() around the...

CVE-2026-53331

The CVE-2026-53331 entry describes a Linux kernel slimbus issue in qcom-ngd-ctrl where tx_lock and slim_controller lock could be acquired in opposite orders, risking a deadlock during SSR/PDR down notification. The report explains that qcom_slim_ngd_down() → slim_report_absent() takes the slim_co...

EUVD-2026-40965

In the Linux kernel, the following vulnerability has been resolved: slimbus: qcom-ngd-ctrl: Avoid ABBA on txlock/ctrl-lock During the SSR/PDR down notification the txlock is taken with the intent to provide synchronization with active DMA transfers. But during this period qcomslimngddown is...

CVE-2026-53327

CVE-2026-53327 affects the Linux kernel, specifically the debugobjects path related to fill_pool() on RT-enabled kernels. The root cause is that fill_pool() may invoke rtlock_lock() while current::pi_blocked_on is set, which can trigger an assertion because a task should block on only one lock to...

EUVD-2026-40961

In the Linux kernel, the following vulnerability has been resolved: debugobjects: Do not fillpool if piblockedon On RT enabled kernels, fillpool ends up calling rtlocklock, which asserts if current::piblockedon is set, because a task can obviously only block on one lock as otherwise the priority...

kernel: ALSA: aloop: Fix racy access at PCM trigger

In the Linux kernel, the following vulnerability has been resolved: ALSA: aloop: Fix racy access at PCM trigger The PCM trigger callback of aloop driver tries to check the PCM state and stop the stream of the tied substream in the corresponding cable. Since both check and stop operations are...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...

httpd: NULL pointer dereference via specially crafted request

A flaw was found in the moddavlock module of httpd. This vulnerability allows a remote unauthenticated attacker to crash the server due to a NULL pointer dereference via a specially crafted request...
