CVE-2026-46067 mm/damon/core: validate damos_quota_goal->nid for node_memcg_{used,free}_bp

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: validate damosquotagoal-nid for nodememcgused,freebp Users can set damosquotagoal-nid with arbitrary value for nodememcgused,freebp. But DAMON core is using those for NODE-DATA without a validation of the value. Th...

CVE-2026-46067

CVE-2026-46067 affects the Linux kernel DAMON core. The issue arises because the code path in mm/damon/core validates the node-datas used by NODE-DATA() relies on damos_quota_goal->nid but does not validate its value, allowing an arbitrary nid to be supplied for node_memcg_{used,free}_bp. This...
