In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: Synchronize timeout work during SQ teardown nvmetauthsqfree() cancels authexpiredwork with canceldelayedwork(). If the work has already started, cancellation does not wait for the callback. Transport teardown can consequently free or reuse the queue containing struct nvmetsq while nvmetauthexpiredwork() still accesses that SQ. Add a teardown-specific helper that synchronously drains the delayed work before freeing authentication state, and use it from nvmetsq_destroy(). Keep the non-synchronous helper for in-band authentication state cleanup, where the SQ owner remains alive.
