Description from the CNA
In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm/si: Don't schedule thermal work when queue isn't initialized When DPM is turned off with the amdgpu.dpm=0 module parameter, the thermal work queue isn't initialized so we shouldn't schedule any work on it. (cherry picked from commit bd018d36171a695952c6d391471c279c9e05c8b2)
