      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: fix locking in hci_conn_request_evt() with HCI_PROTO_DEFER\n\nWhen protocol sets HCI_PROTO_DEFER, hci_conn_request_evt() calls\nhci_connect_cfm(conn) without hdev->lock. Generally hci_connect_cfm()\nassumes it is held, and if conn is deleted concurrently -> UAF.\n\nOnly SCO and ISO set HCI_PROTO_DEFER and only for defer setup listen,\nand HCI_EV_CONN_REQUEST is not generated for ISO.  In the non-deferred\nlistening socket code paths, hci_connect_cfm(conn) is called with\nhdev->lock held.\n\nFix by holding the lock.",
