Last modified
CVE-2022-50842 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Check whether transferred 2D BO is shmem Transferred 2D BO always must be a shmem BO. Add check for that to prevent NULL dereference if userspace passes a VRAM BO.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
