Linux Kernel: AMD GPU Thermal Work Queue Scheduling Bug (CVE-2026-98898)
CVE-2026-98898 Published on October 23, 2026
drm/amd/pm/si: Don't schedule thermal work when queue isn't initialized
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.
