@ctoney@fosstodon.org Just wondering the same. Seems Ubuntu LTS remains non-fixed?
Ubuntu's grandmother Debian seems on top of things.
Tested the oft cited PoC (https://github.com/theori-io/copy-fail-CVE-2026-31431/blob/main/copy_fail_exp.py) on patched 6.12.85+deb13-amd64 for Trixie:
```
root@cake:~# su - eat
eat@cake:~$ vim foo.py
eat@cake:~$ cat foo.py | python3 && su
Password: su: Authentication failure

@JulianOliver@mastodon.social possibly remains non-fixed. I was seeing info that certain kernel versions may have patches for Ubuntu, then tried to get the official Canonical documentation but no luck. I see they just added some status updates. https://status.canonical.com/
