      <title>CVE-2026-52928 — af_unix: Reject SIOCATMARK on non-stream sockets</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-52928</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;af_unix: Reject SIOCATMARK on non-stream sockets&lt;/p&gt;
&lt;p&gt;SIOCATMARK reports whether the receive queue is at the urgent mark for
MSG_OOB.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;Return -EOPNOTSUPP for non-stream sockets before checking the receive
queue.&lt;/p&gt;</description>
