CVE-2023-53002

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

drm/i915: Fix a memory leak with reused mmap_offset

drm_vma_node_allow() and drm_vma_node_revoke() should be called in balanced pairs. We call drm_vma_node_allow() once per-file everytime a user calls mmap_offset, but only call drm_vma_node_revoke once per-file on each mmap_offset. As the mmap_offset is reused by the client, the per-file vm_count may remain non-zero and the rbtree leaked.

Call drm_vma_node_allow_once() instead to prevent that memory leak.
