CVE-2026-53005 af_unix: Drop all SCM attributes for SOCKMAP.

In the Linux kernel, the following vulnerability has been resolved: afunix: Drop all SCM attributes for SOCKMAP. SOCKMAP can hide inflight fd from AFUNIX GC. When a socket in SOCKMAP receives skb with inflight fd, skpsockverdictdataready looks up the mapped socket and enqueue skb to its...

CVE-2026-53005

CVE-2026-53005 affects the Linux kernel af_unix SOCKMAP feature.
