  "details": "In the Linux kernel, the following vulnerability has been resolved:  mm: fix deferred split queue races during migration  migrate_folio_move() records the deferred split queue state from src and replays it on dst.  Replaying it after remove_migration_ptes(src, dst, 0) makes dst visible before it is requeued, so a concurrent rmap-removal path can mark dst partially mapped and trip the WARN in deferred_split_folio().  Move the requeue before remove_migration_ptes() so dst is back on the deferred split queue before it becomes visible again.  Because migration still holds dst locked at that point, teach deferred_split_scan() to requeue a folio when folio_trylock() fails.  Otherwise a fully mapped underused folio can be dequeued by the shrinker and silently lost from split_queue.  [ziy@nvidia.com: move the comment]",
