How to fix?

Upgrade SLES:15.6 kernel-docs to version 6.4.0-150600.23.30.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs 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 null pointers before using dc->clk_mgr

[WHY & HOW] dc->clk_mgr is null checked previously in the same function, indicating it might be null.

Passing "dc" to "dc->hwss.apply_idle_power_optimizations", which dereferences null "dc->clk_mgr". (The function pointer resolves to "dcn35_apply_idle_power_optimizations".)

This fixes 1 FORWARD_NULL issue reported by Coverity.
