If sk is an IPv4 socket,\nbut the connect function is called with an IPv6 address,\nthe function calipso_sock_setattr() is triggered.\nInside this function, the following code is executed:\n\nsk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL;\n\nSince sk is an IPv4 socket, pinet6 is NULL, leading to a\nnull pointer dereference.\n\nThis patch fixes the issue by checking if
