Technical description

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()

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
