CVE-2023-53001

In the Linux kernel, the following vulnerability has been resolved:

drm/drm_vma_manager: Add drm_vma_node_allow_once()

Currently there is no easy way for a drm driver to safely check and allow drm_vma_offset_node for a drm file just once. Allow drm drivers to call non-refcounted version of drm_vma_node_allow() so that a driver doesn't need to keep track of each drm_vma_node_allow() to call subsequent drm_vma_node_revoke() to prevent memory leak.
