How to fix?

Upgrade SLES:15.6 kernel-default-base to version 6.4.0-150600.23.30.1.150600.12.12.6 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:15.6 relevant fixed versions and status.

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

drm/amd/display: Check link_res->hpo_dp_link_enc before using it

[WHAT & HOW] Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res without initializing hpo_dp_link_enc and it is necessary to check for null before dereferencing.

This fixes 2 FORWARD_NULL issues reported by Coverity.
