There is no fixed version for Centos:10 libperf.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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.
