How to fix?

There is no fixed version for Centos:10 perf.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf 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: Return immediately when manage_oob() returns NULL for 0-length buffer.

Fahad Alharbi reported that recv(0, MSG_PEEK) triggers busy-wait in unix_stream_read_generic() if recv() is blocking and the last skb in the queue is MSG_OOB skb.

In such a situation, TCP returns 0 immediately regardless of blocking or non-blocking.

Let's follow the behaviour.
