CVE-2026-53347 Details
Description
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 vulnerability in the Linux kernel's virtio-gpu driver can lead to a kernel crash. This issue occurs when the driver is built with KMS (Kernel Mode Setting) support disabled. In such cases, the driver removal process attempts to access uninitialized data, causing a kernel crash. The problem arises because the driver does not properly initialize KMS-related features before removal. The vulnerability has been addressed by modifying the driver removal process to skip certain operations when KMS is unavailable, preventing the access of uninitialized data and the subsequent kernel crash.
Users can recompile the virtio-gpu driver with KMS support enabled to avoid this vulnerability. Instructions for building the driver with KMS support can be found in the Linux kernel documentation.
