CVE-2026-89595

A flaw was found in the Linux kernel's fsnotify subsystem, affecting fanotify and inotify. A race condition can occur during concurrent updates to event marks, where the object mask becomes stale. This can lead to a denial of service or information disclosure, as events such as file modifications...

CVE-2026-89643

A flaw was found in the Linux kernel's audit subsystem. When fsnotify rules are automatically removed, the system incorrectly manages memory references, leading to a situation where freed memory can be accessed again. This memory corruption vulnerability could allow a local attacker to cause a...

CVE-2026-89643

In the Linux kernel, the following vulnerability has been resolved: audit: avoid dropping live tree ref on fsnotify rule autoremove auditdelrule is used for both netlink deletion templates and internal fsnotify autoremove. The former passes a parsed template which owns a temporary tree reference;...

CVE-2026-89595

In the Linux kernel, the following vulnerability has been resolved: fsnotify: Fix stale object mask after concurrent mark updates When a mark gets a new event bit, fanotify and inotify may avoid recalculating the object mask if the cached aggregate already contains that bit. This is racy with a...

CVE-2026-89643

A use-after-free vulnerability exists in the Linux kernel's audit subsystem . The function audit_del_rule() unconditionally calls audit_put_tree() at its end, assuming it always handles a temporary parser-owned tree reference. However, when invoked via fsnotify autoremove for mixed AUDIT_DIR + AU...

CVE-2026-89595

CVE-2026-89595 is a race condition in the Linux kernel's fsnotify subsystem affecting both fanotify and inotify . When concurrent updates modify different marks on the same connector, a scanning thread can read a mark before a new event bit is added, while the updater skips recalculation, leaving...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: iouring/rw: Defer fsnotify calls to task context. We cannot defer these calls outside of the kiocb completion, as that might be off-soft/hard IRQ context. We should defer the calls until we process the taskwork for this reques...
