How to fix?

Upgrade SLES:15.7 kernel-default-base to version 6.4.0-150700.53.81.1.150700.17.45.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: detect_link_and_local_sink: DP alt mode timeout path leaks prev_sink reference

prev_sink is unconditionally retained via dc_sink_retain at function entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT returns false without releasing prev_sink. All other return paths in the function correctly call dc_sink_release(prev_sink), making this the only missing cleanup.

(cherry picked from commit 45510cf662dcf46b5d8926d454f338809f107b9d)
