CVE-2026-52928

A flaw was found in the Linux kernel's afunix component. This vulnerability involves the incorrect handling of the SIOCATMARK operation when used with non-stream sockets, such as SOCKDGRAM and SOCKSEQPACKET. These socket types did not properly reject SIOCATMARK, an operation intended only for...

EUVD-2026-38698

In the Linux kernel, the following vulnerability has been resolved: afunix: Reject SIOCATMARK on non-stream sockets SIOCATMARK reports whether the receive queue is at the urgent mark for MSGOOB. In AFUNIX, MSGOOB is supported only for SOCKSTREAM sockets. SOCKDGRAM and SOCKSEQPACKET reject MSGOOB ...

CVE-2026-52928

The CVE-2026-52928 entry concerns the Linux kernel’s AF_UNIX handling of SIOCATMARK, where MSG_OOB is valid only on SOCK_STREAM. The root cause is that SIOCATMARK was evaluated against the receive queue on non-stream sockets; the fix ensures non-stream sockets return -EOPNOTSUPP before inspecting...
