When target_nid is invalid\n(including the scheme default NUMA_NO_NODE / -1), damon_migrate_pages()\nreturns early without putting the folios back to the LRU.\n\nCallers then discard the list head while those folios remain isolated with\nan extra reference taken by folio_isolate_lru().  The pages stay off the\nLRU for as long as the mapping exists (anon active+inactive counts drop\nwhile RSS does not), and the leftover references can pin the pages after\nthe mapping is gone.\n\nPut the folios back on the invalid-nid path so ignored migration requests\nstill return them to the LRU.","published":"2026-08-22T16:16:38.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06031,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
