How to fix?

Upgrade Centos:7 kernel-rt-trace-devel to version 0:3.10.0-1160.53.1.rt56.1193.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace-devel package and not the kernel-rt-trace-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.
