In the Linux kernel, the following vulnerability has been resolved: drm/msm: always recover the gpu Previously, in case there was no more work to… (CVE-2026-53377)
A vulnerability in the Linux kernel's drm/msm GPU driver was resolved by changing the recovery behavior. Previously, if no more work was queued, the recovery worker would not trigger GPU recovery, relying instead on the GPU suspending and resuming. This could leave the GPU in a hung state, causing repeated timeouts. The fix ensures the GPU is always recovered regardless of queued work.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel drm/msm driver involved the recovery mechanism for the GPU. When the GPU hung and there was no additional work queued, the recovery worker would not initiate recovery, assuming the GPU would suspend and resume. However, this assumption could fail, leaving the GPU hung and causing repeated timeouts. The patch changes the logic to always recover the GPU, preventing it from remaining in a hung state.
Potential Impact
If exploited, the GPU could remain in a hung state, potentially causing system instability or denial of service due to repeated GPU timeouts. This affects the reliability of GPU operations but does not indicate privilege escalation or data compromise.
Mitigation Recommendations
A patch has been applied to the Linux kernel drm/msm driver to always recover the GPU regardless of queued work. Users should update to the fixed kernel version containing this patch. No additional mitigation steps are indicated.
