Summary
In the Linux kernel, the following vulnerability has been resolved: s390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct() Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount (skb->users) and iucv_sock_recvmsg() does not decrement skb refcount at exit. This results in skb memory leak in skb_queue_purge() and WARN_ON in iucv_sock_destruct() during socket close. To fix this decrease skb refcount by one if MSG_PEEK is set in order to prevent memory leak and WARN_ON.

Pasar el indicador MSG_PEEK a skb_recv_datagram() incrementa el recuento de referencias de skb (skb-\u0026gt;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.
