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