Hi Linux kernel maintainers,

We found and validated an issue in IP tunnel headroom accounting. The bug is
reachable by a non-root user via user and net namespace.
We've tested it, and it should not affect any other functionality.

We will provide detailed information about the bug
in this email, along with a PoC to trigger it.
