Summary
ip_vti: fix potential slab-use-after-free in decode_session6
Details

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

ipvti: fix potential slab-use-after-free in decodesession6

When ipvti device is set to the qdisc of the sfb type, the cb field of the sent skb may be modified during enqueuing. Then, slab-use-after-free may occur when ipvti device sends IPv6 packets. As commit f855691975bb ("xfrm6: Fix the nexthdr offset in decodesession6.") showed, xfrmdecodesession was originally intended only for the receive path. IP6CB(skb)->nhoff is not set during transmission. Therefore, set the cb field in the skb to 0 before sending packets.
