Title
udplite: Fix null-ptr-deref in __udp_enqueue_schedule_skb().
Summary
In the Linux kernel, the following vulnerability has been resolved: udplite: Fix null-ptr-deref in __udp_enqueue_schedule_skb(). syzbot reported null-ptr-deref of udp_sk(sk)->udp_prod_queue. [0] Since the cited commit, udp_lib_init_sock() can fail, as can udp_init_sock() and udpv6_init_sock(). Let's handle the error in udplite_sk_init() and udplitev6_sk_init().
