Summary
In the Linux kernel, the following vulnerability has been resolved: drm/ttm: Fix ttm_bo_shrink() infinite LRU walk on backup failure Apply the same fix as b2ed01e7ad ("drm/ttm: Fix ttm_bo_swapout() infinite LRU walk on swapout failure") to the ttm_bo_shrink() path. Move del_bulk_move from before the backup to after success only, using ttm_resource_del_bulk_move_unevictable() since the resource is now unevictable once fully backed up.
