# Linux kernel: AMD SI GPU thermal work scheduled on uninitialized queue

With DPM disabled via the amdgpu.dpm=0 module parameter, the AMD Southern Islands driver could schedule thermal work on a work queue that was never initialized. The sources describe a fix that skips scheduling in that case; they do not describe an attacker-reachable impact.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- unknown

## Fix

- Update to a Linux kernel release that includes upstream commit bd018d36171a695952c6d391471c279c9e05c8b2 (version unknown from sources)

## Timeline

- 2026-10-23T21:57:33+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-98898

## From the sources

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)
