Once the cluster buffer no longer\nprotects the log item from reclaim, the log item may be freed by\nbackground reclaim or the dquot shrinker. The subsequent spin_lock()\ncall dereferences lip->li_ailp, which is a use-after-free.\n\nFix this by saving the ailp pointer in a local variable while the AIL\nlock is held and the log item is guaranteed to be valid.","state":0,"publishedAt":"2026-04-22T13:53:48.242+00:00","modifiedAt":"2026-10-19T18:35:49.366+00:00","affected":[{"ecosystem":"Vendor
