In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix possible UAF in ip6_finish_output2()
If skb_expand_head() returns NULL, skb has been freed
and associated dst/idev could also have been freed.
We need to hold rcu_read_lock() to make sure the dst and
associated idev are alive.
