The Update Conundrum
the.unknown-universe.co.uk
How a “kept back” Proxmox kernel left my home lab exposed to CVE‑2026‑31431 — why I now check upgradable packages and use apt full‑upgrade.

I’ve been running my home lab since 2021 and honestly thought my update routine was solid: apt update && apt upgrade, reboot, job done.

Turns out I was wrong. I was checking CVE‑2026‑31431 (Copy Fail) this morning and realised that despite my “successful” updates, I was still running a vulnerable kernel from March.

I’ve had to rethink how I handle host updates. If you’re relying on a standard upgrade and a reboot to keep Proxmox or Debian hosts safe, you might want to check if yours is lying to you as well.

      Sure in the gigantic wall of text. Also it doesn’t tell you why, or what to do about it. All they’d have to do is say “run dist-upgrade to update these packages.”

        It is literally in the summary that gets presented in the last few lines before you have to press Y to continue.

        Since you are already overwhelmed by the wall of text, you would probably not read the suggestion antways.
