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.
