In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Fix driver removal with disabled KMS DRM atomic and modesetting… (CVE-2026-53347)
A vulnerability in the Linux kernel's drm/virtio driver occurs when KMS (Kernel Mode Setting) is disabled. The issue involves uninitialized DRM atomic and modesetting components, which leads to accessing uninitialized data during driver removal or unbinding, causing a kernel crash. The flaw is fixed by skipping the shutdown of the atomic core when KMS is unavailable.
AI Analysis
Technical Summary
The Linux kernel's drm/virtio driver does not properly handle driver removal when KMS is disabled. Specifically, DRM atomic and modesetting are not initialized in this configuration, but the driver attempts to shut down the atomic core during removal, resulting in access to uninitialized data and a kernel crash. The fix involves conditionally skipping the atomic core shutdown if KMS is not available, preventing the crash.
Potential Impact
This vulnerability causes a denial of service via kernel crash when the virtio-gpu driver is built with disabled KMS and the driver is removed or unbound. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is applied, avoid removing or unbinding the virtio-gpu driver when KMS is disabled to prevent kernel crashes.
