The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/virtio: fix memory leak of fence event on execbuffer failure virtio_gpu_execbuffer_ioctl() reserves a     DRM event with drm_event_reserve_init() when VIRTGPU_EXECBUF_RING_IDX selects a ring that userspace has     enabled polling for. virtio_gpu_init_submit() does this before the BO handles, the command buffer, the     syncobj arrays and the in-fence are processed, so every later error path runs with the event already     pending, including plain argument validation failures such as an invalid bo_handle or an in-syncobj that     carries no fence. On those paths, virtio_gpu_cleanup_submit() drops the out-fence without cancelling the     event. The fence is freed without ever having been emitted, taking the only driver-side pointer to the     event with it. Closing the DRM file does not help. drm_events_release() unlinks pending events but     deliberately leaves the freeing to the driver's later drm_send_event(), which never runs for an orphaned     event, so the allocation is leaked permanently. Found when fuzzing the virtio driver with Syzkaller: BUG:
