    "summary": "In the Linux kernel, the following vulnerability has been resolved: nvme: fix admin request_queue lifetime The namespaces can access the controller's admin request_queue, and stale references on the namespaces may exist after tearing down the controller. Ensure the admin request_queue is active by moving the controller's 'put' to after all controller references have been released to ensure no one is can access the request_queue.
