      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: s390/iucv: MSG_PEEK provoca una p\u00e9rdida de memoria en iucv_sock_destruct(). Pasar el indicador MSG_PEEK a skb_recv_datagram() incrementa el recuento de referencias de skb (skb-&gt;users) y iucv_sock_recvmsg() no decrementa el recuento de referencias de skb al salir. Esto da como resultado una p\u00e9rdida de memoria de skb en skb_queue_purge() y WARN_ON en iucv_sock_destruct() durante el cierre del socket. Para solucionar esto, disminuya el recuento de referencias de skb en uno si MSG_PEEK est\u00e1 configurado para evitar la p\u00e9rdida de memoria y WARN_ON.
