- Summary
- CVE-2026-52928 affecting package kernel for versions less than 6.6.144.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Reject SIOCATMARK on non-stream sockets
SIOCATMARK reports whether the receive queue is at the urgent mark for MSG_OOB.
In AF_UNIX, MSG_OOB is supported only for SOCK_STREAM sockets. SOCK_DGRAM and SOCK_SEQPACKET reject MSG_OOB in sendmsg() and recvmsg(), so they should not support SIOCATMARK either.
Return -EOPNOTSUPP for non-stream sockets before checking the receive queue.
