Summary
drm/ttm: fix bulk_move corruption when adding a entry
Details

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

drm/ttm: fix bulk_move corruption when adding a entry

When the resource is the first in the bulkmove range, adding it again (thus moving it to the tail) will corrupt the list since the first pointer is not moved. This eventually lead to null pointer deref in ttmlrubulkmove_del()
