  "summary": "nvmet-auth: Synchronize timeout work during SQ teardown",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvmet-auth: Synchronize timeout work during SQ teardown\n\nnvmet_auth_sq_free() cancels auth_expired_work with\ncancel_delayed_work(). 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.",
