En el siguiente fallo [1], syzbot logró activar una división por cero en tcp_rcv_space_adjust(). Un socket realiza las siguientes transiciones de estado, sin siquiera llamar a tcp_init_transfer(), lo que significa que tampoco se llama a tcp_init_buffer_space(). TCP_CLOSE connect() TCP_SYN_SENT TCP_SYN_RECV Shutdown() -&gt; tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1 Para solucionar este problema, cambie tcp_shutdown() para no realizar una transición TCP_SYN_RECV -&gt; TCP_FIN_WAIT1, lo que de todos modos no tiene sentido. Cuando tcp_rcv_state_process() luego cambie el estado del socket de TCP_SYN_RECV a TCP_ESTABLISH, mire sk-&gt;sk_shutdown para finalmente ingresar al estado TCP_FIN_WAIT1 y envíe un paquete FIN desde un estado de socket sano. Esto significa que ahora se puede llamar a tcp_send_fin() desde el contexto BH y debe usar asignaciones GFP_ATOMIC.
