NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool6.18-debuginfo package and not the bpftool6.18-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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.
