      "title": "Bluetooth: RFCOMM: avoid socket lock inversion in listener cleanup",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: RFCOMM: avoid socket lock inversion in listener cleanup\n\nrfcomm_sock_cleanup_listen() closes unaccepted child sockets through\nrfcomm_sock_close(), which takes the child socket lock before\nrfcomm_dlc_close() acquires rfcomm_mutex. The RFCOMM worker takes these\nlocks in reverse order while handling connections and DLC state changes,\nso lockdep reports a possible deadlock.\n\nClose dequeued children without taking their socket lock. The accept queue\nowns a reference to each child, and bt_accept_dequeue() locks the child\nwhile unlinking it and clearing its parent pointer.\n\nDropping the child lock makes it important to prevent a concurrent\nrfcomm_connect_ind() from enqueueing a new child after cleanup observes an\nempty queue. Set a listening socket to BT_CLOSED while its lock is still\nheld, before dropping the lock and draining the queue. The state check in\nrfcomm_connect_ind() then rejects new children once cleanup starts.",
