Revision 988dc4a9a3b66be75b30405a5494faf0dc7cffb6 authored by Lorenzo Bianconi on 09 April 2019, 09:47:20 UTC, committed by David S. Miller on 11 April 2019, 06:02:23 UTC
gue tunnels run iptunnel_pull_offloads on received skbs. This can
determine a possible use-after-free accessing guehdr pointer since
the packet will be 'uncloned' running pskb_expand_head if it is a
cloned gso skb (e.g if the packet has been sent though a veth device)
Fixes: a09a4c8dd1ec ("tunnels: Remove encapsulation offloads on decap")
