How to fix?

Upgrade SLES:15.2 kernel-livepatch-5_3_18-24_67-default to version 8-2.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-24_67-default package and not the kernel-livepatch-5_3_18-24_67-default package as distributed by SLES. See How to fix? for SLES:15.2 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.
