Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Check socket flag instead of hcon This fixes the following Smatch static checker warning: net/bluetooth/iso.c:1364 iso_sock_recvmsg() error: we previously assumed 'pi->conn->hcon' could be null (line 1359) net/bluetooth/iso.c 1347 static int iso_sock_recvmsg(struct socket *sock, struct msghdr *msg, 1348 size_t len, int flags) 1349 { 1350 struct sock *sk = sock->sk; 1351 struct iso_pinfo *pi = iso_pi(sk); 1352 1353 BT_DBG("sk %p", sk); 1354 1355 if (test_and_clear_bit(BT_SK_DEFER_SETUP, &bt_sk(sk)->flags)) { 1356 lock_sock(sk); 1357 switch (sk->sk_state) { 1358 case BT_CONNECT2: 1359 if (pi->conn->hcon && ^^^^^^^^^^^^^^ If ->hcon is NULL 1360 test_bit(HCI_CONN_PA_SYNC, &pi->conn->hcon->flags)) { 1361 iso_conn_big_sync(sk); 1362 sk->sk_state = BT_LISTEN; 1363 } else { --> 1364 iso_conn_defer_accept(pi->conn->hcon); ^^^^^^^^^^^^^^ then we're toast 1365 sk->sk_state = BT_CONFIG; 1366 } 1367 release_sock(sk); 1368 return 0; 1369 case BT_CONNECTED: 1370 if (test_bit(BT_SK_PA_SYNC,
