EUVD-2026-38873

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. The issue arises from improper handling of SCM attributes when data is passed to SOCKMAP, enabling a use-after-free and inflight-file-descriptor leaks due to inability of GC paths to inspect psock queues after skb redirection. Multi...
