After the recursive call returns, list_for_each_entry() advances\nby reading list.next from the removed child.\n\nIf free_ei() drops the final reference, release_ei() reuses the list/rcu\nunion to queue an SRCU callback. The child may be freed before that read.\nThe eventfs_mutex serializes list updates, but it does not keep the removed\nchild alive or prevent the SRCU callback from running.\n\nUse list_for_each_entry_safe() to save the next sibling before recursively\nremoving the current child.","published":"2026-08-22T16:16:33.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00125,"percentile":0.02189,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%).
