If the work has already started, cancellation does\nnot wait for the callback. Transport teardown can consequently free or\nreuse the queue containing struct nvmet_sq while\nnvmet_auth_expired_work() still accesses that SQ.\n\nAdd a teardown-specific helper that synchronously drains the delayed work\nbefore freeing authentication state, and use it from nvmet_sq_destroy().\nKeep the non-synchronous helper for in-band authentication state cleanup,\nwhere the SQ owner remains alive.","state":0,"publishedAt":"2026-09-16T10:32:50.306+00:00","modifiedAt":"2026-10-19T08:55:43.826+00:00","affected":[{"ecosystem":"Vendor
