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.

A flaw was found in the Linux kernel's drm/virtio driver. When the virtio-gpu driver is configured with Kernel Mode Setting (KMS) disabled, the display-related atomic and modesetting components are not properly initialized. This can lead to the system attempting to access uninitialized data during driver removal or unbinding, resulting in a kernel crash. This vulnerability could potentially lead to a denial of service.
