A flaw was found in the Linux kernel's SELinux (Security-Enhanced Linux) socket permission helpers. In configurations where multiple Linux Security Modules (LSMs) are active, the system may incorrectly access socket security data. This can lead to invalid security identifiers (SIDs) and class values being used in Access Vector Cache (AVC) checks, potentially allowing a bypass of intended security policies.
