{"apiVersion":"1.0","identifier":"CVE-2026-74644","description":"In the Linux kernel, the following vulnerability has been resolved: mm/damon/ops-common: putback folios on invalid migrate nid damon_pa_migrate() and damos_va_migrate() isolate folios into a local list and then call damon_migrate_pages(). When target_nid is invalid (including the scheme default NUMA_NO_NODE / -1), damon_migrate_pages() returns early without putting the folios back to the LRU. Callers then discard the list head while those folios remain isolated with an extra reference taken by folio_isolate_lru(). The pages stay off the LRU for as long as the mapping exists (anon active+inactive counts drop while RSS does not), and the leftover references can pin the pages after the mapping is gone. Put the folios back on the invalid-nid path so ignored migration requests still return them to the LRU.","publishedAt":"2026-08-22T16:16:37","lastModifiedAt":"2026-08-23T13:16:48","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74644","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00168,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74644","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74644","en":"https://www.redsauce.net/en/cves/CVE-2026-74644","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74644","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74644","de":"https://www.redsauce.net/de/cves/CVE-2026-74644","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74644","el":"https://www.redsauce.net/el/cves/CVE-2026-74644"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74644"}}
