- Summary
- mm/damon/ops-common: putback folios on invalid migrate nid
- Details
-
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.
