Name: re2c
CVEs: CVE-2022-23901
CVSSs: 9.8
Action Needed: update to >= 3.1

Summary: A stack overflow re2c 2.2 exists due to infinite recursion issues in src/dfa/dead_rules.cc.

Note, even if it only says re2c 2.2, re2c 2.0.3 in Flatcar still looks affected.

As re2c is only included in the SDK, it has LOW severity.

Yes, and they reimplemented it with a PR, and merged as commit. So we just need to update to 3.1.
Weekly updates are already syncing re2c. Flatcar does not have the new version just because 3.1 is still unstable.
Well, after all it is a SDK-only package.
