Description
A flaw was found in the Linux kernel's Security-Enhanced Linux (SELinux) subsystem. The per-task avdcache (access vector cache) incorrectly stored and reused auditing information. This prevented some critical security permission checks, such as directory write operations, from being properly audited. As a result, an attacker could potentially perform actions without them being recorded in the system's audit logs, leading to a security bypass of auditing mechanisms.
