  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: phonet: do not BUG_ON() in pn_socket_autobind() on failed bind  syzbot reported a kernel BUG triggered from pn_socket_sendmsg() via pn_socket_autobind():    kernel BUG at net/phonet/socket.c:213!   RIP: 0010:pn_socket_autobind net/phonet/socket.c:213 [inline]   RIP: 0010:pn_socket_sendmsg\u002B0x240/0x250 net/phonet/socket.c:421   Call Trace:    sock_sendmsg_nosec\u002B0x112/0x150 net/socket.c:797    __sock_sendmsg net/socket.c:812 [inline]    __sys_sendto\u002B0x402/0x590 net/socket.c:2280    ...  pn_socket_autobind() calls pn_socket_bind() with port 0 and, on -EINVAL, assumes the socket was already bound and asserts that the port is non-zero:    err = pn_socket_bind(sock, ..., sizeof(struct sockaddr_pn));   if (err != -EINVAL)           return err;   BUG_ON(!pn_port(pn_sk(sock-\u003Esk)-\u003Esobject));   return 0; /* socket was already bound */  However pn_socket_bind() also returns -EINVAL when sk-\u003Esk_state is not TCP_CLOSE, even when the socket has never been bound and pn_port() is still 0.  In that case the BUG_ON() fires and panics the kernel from a user-triggerable path.  Treat the \u0022bind returned -EINVAL but pn_port() is still 0\u0022 case as a regular error and propagate -EINVAL to the caller instead of crashing. Existing callers already translate a non-zero return from pn_socket_autobind() into -ENOBUFS/-EAGAIN, so returning -EINVAL here only changes behaviour from panic to a normal errno.",
