CVE-2026-23394

A flaw was found in the Linux kernel's afunix component. A race condition exists between the MSGPEEK operation and the garbage collection process. This can allow a local user to cause the garbage collector to incorrectly purge the receive queue of an alive socket, potentially leading to a denial ...
