Description

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.

Affected configurations

• linux linux kernel (< 5.10.227) • linux linux kernel (>= 5.11 < 5.15.168) • linux linux kernel (>= 5.16 < 6.1.113) • linux linux kernel (>= 6.2 < 6.6.55) • linux linux kernel (>= 6.7 < 6.10.14) • linux linux kernel (>= 6.11 < 6.11.3)
