Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to out-of-bounds memory access in the DAMON core when processing a user-supplied damos_quota_goal->nid value for node_memcg_used_bp or node_memcg_free_bp. A local user can supply an invalid node id to trigger out-of-bounds memory access and cause a denial of service.
Exploitation requires access to the DAMON user-space interface.
