NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-extra package and not the kernel-uek-debug-modules-extra package as distributed by Oracle. See How to fix? for Oracle:8 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.
