CVE-2026-53190

CVE-2026-53190 concerns a Linux kernel vulnerability in the drm/virtio path where a refcount leak could occur in error handling of virtio_gpu_dma_fence_wait(). The root cause is that dma_fence_unwrap_for_each() calls dma_fence_unwrap_first(), which assigns cursor->chain = dma_fence_get(head) (...

PT-2026-52286

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A reference count leak occurs in the virtio gpu dma fence wait function within the drm/virtio component. The issue arises because dma fence unwrap for each calls dma fence unwrap first,...
