NVD

In the Linux kernel, the following vulnerability has been resolved:

ipv6: fix possible UAF in icmpv6 rcv()

Caching saddr and daddr before pskb pull() is problematic since skb->head can change.

Remove these temporary variables:

• We only access &ipv6 hdr(skb)->saddr and &ipv6 hdr(skb)->daddr when net dbg ratelimited() is called in the slow path.
• Avoid potential future misuse after pskb pull() call.
