CVE-2026-98394

A flaw was found in the Linux kernel's UNIX domain socket afunix implementation. When a blocking receive operation is performed using a zero-length buffer and the peek flag on a socket where the last queued message contains out-of-band OOB data, the kernel fails to return properly. A local attack...

CVE-2026-98394

The Linux kernel contains a vulnerability in af_unix where recv(0, MSG_PEEK) triggers a busy-wait in unix_stream_read_generic(). This occurs when a blocking recv() is called and the final socket buffer (skb) in the queue is an MSG_OOB skb, but manage_oob() returns NULL for a 0-length buffer. The ...
