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.","published":"2026-09-16T10:32:50.306Z","modified":"2026-09-16T10:32:50.306Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/664022fa1c93f4eba09ef5ee02411b9709dd7a93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3c126a6142a1335bc8c34a5607c39cf01daf295"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c17c87bde6d6f5252a6a6f0a94b2430164aa28d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7555ddd60af72df2862dd8f9b730a9848577edda"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb4f9127a2b8a152743f1ee597627e2f69cb54fe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eaa948c0e19b1bb2d93262207bca0c3d19cc3406"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T10:32:50.306Z"}}
