# CVE-2026-100077

> 5.5 MEDIUM

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Recover HW before retire hung submit

During recovery, it is not safe to retire the hung submit before we
recover the GPU. Retiring the submit triggers BO free and that can
result in GPU pagefaults since the GPU may be actively accessing those
BOs.

To fix this, retire the submits after gpu recovery is complete in
recover_worker().

## Schwachstellen-Klasse

- **CWE-416** — Use After Free
  The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

## Patch verfügbar (OSV)

- Kernel ≥ 6.6.160
- Kernel ≥ 6.12.114
- Kernel ≥ 6.18.52
- Kernel ≥ 7.2.6
