"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: Fix possible deadlock in rfcomm_sk_state_change\n\nsyzbot reports a possible deadlock in rfcomm_sk_state_change [1].\nWhile rfcomm_sock_connect acquires the sk lock and waits for\nthe rfcomm lock, rfcomm_sock_release could have the rfcomm\nlock and hit a deadlock for acquiring the sk lock.\nHere's a simplified flow:\n\nrfcomm_sock_connect:\n lock_sock(sk)\n rfcomm_dlc_open:\n rfcomm_lock()\n\nrfcomm_sock_release:\n rfcomm_sock_shutdown:\n rfcomm_lock()\n __rfcomm_dlc_close:\n rfcomm_k_state_change:\n\t lock_sock(sk)\n\nThis patch drops the sk lock before calling rfcomm_dlc_open to\navoid the possible deadlock and holds sk's reference count to\nprevent use-after-free after rfcomm_dlc_open completes."
