Summary
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 bulk_move 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 ttm_lru_bulk_move_del()
