Summary
net: xfrm: reject unrepresentable espintcp transport headers
Details

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

net: xfrm: reject unrepresentable espintcp transport headers

ESP-in-TCP can hand xfrm packets whose transport header offset no longer fits after the stream parser trims the TCP envelope. The plain transport header reset truncates that offset and triggers the skb warning path.

Use the careful transport-header helper and drop the skb through the existing XFRM error path when the offset cannot be represented.
