Summary

In the Linux kernel, the following vulnerability has been resolved: tunnels: do not assume mac header is set in skb_tunnel_check_pmtu() Recently added debug in commit f9aefd6b2aa3 ("net: warn if mac header was not set") caught a bug in skb_tunnel_check_pmtu(), as shown in this syzbot report [1]. In ndo_start_xmit() paths, there is really no need to use skb->mac_header, because skb->data is supposed to point at it.
