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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/460181e4bb47a57776c64f0832c2096de8878cb3","https://git.kernel.org/stable/c/5deb65c34e682e7c5f5df417a70e223e8fcc5f5a","https://git.kernel.org/stable/c/7001c0a1bc9018cd5b2b72ebebb216d738b2ec81","https://git.kernel.org/stable/c/cfef454862b7d2776e0955b873dd59af6b47cfcb"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-74644","score":0.00168,"percentile":0.06021,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
