In stacked configurations that assumption does not hold. If another LSM allocates socket blob storage before SELinux, these helpers may read the wrong blob and feed invalid SID and class values into AVC checks. Use selinux_sock() instead of accessing sk->sk_security directly. Join the discussion | GCVE Database | 05/28/2026, 10:16:00 UTC Added: 07/17/2026, 10:20:57 UTC |
