Details

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

drm/virtio: Fix driver removal with disabled KMS

DRM atomic and modesetting aren't initialized if virtio-gpu driver built with disabled KMS, leading to access of uninitialized data on driver removal/unbinding and crashing kernel. Fix it by skipping shutting down atomic core with unavailable KMS.

Severity

5.5 (Medium)
