      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: phonet: do not BUG_ON() in pn_socket_autobind() on failed bind\n\nsyzbot reported a kernel BUG triggered from pn_socket_sendmsg() via\npn_socket_autobind():\n\n  kernel BUG at net/phonet/socket.c:213!\n  RIP: 0010:pn_socket_autobind net/phonet/socket.c:213 [inline]\n  RIP: 0010:pn_socket_sendmsg+0x240/0x250 net/phonet/socket.c:421\n  Call Trace:\n   sock_sendmsg_nosec+0x112/0x150 net/socket.c:797\n   __sock_sendmsg net/socket.c:812 [inline]\n   __sys_sendto+0x402/0x590 net/socket.c:2280\n   ...\n\npn_socket_autobind() calls pn_socket_bind() with port 0 and, on\n-EINVAL, assumes the socket was already bound and asserts that the\nport is non-zero:\n\n  err = pn_socket_bind(sock, ..., sizeof(struct sockaddr_pn));\n  if (err != -EINVAL)\n          return err;\n  BUG_ON(!pn_port(pn_sk(sock->sk)->sobject));\n  return 0; /* socket was already bound */\n\nHowever pn_socket_bind() also returns -EINVAL when sk->sk_state is not\nTCP_CLOSE, even when the socket has never been bound and pn_port() is\nstill 0.  In that case the BUG_ON() fires and panics the kernel from a\nuser-triggerable path.\n\nTreat the \"bind returned -EINVAL but pn_port() is still 0\" case as a\nregular error and propagate -EINVAL to the caller instead of crashing.\nExisting callers already translate a non-zero return from\npn_socket_autobind() into -ENOBUFS/-EAGAIN, so returning -EINVAL here\nonly changes behaviour from panic to a normal errno.",
