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.

Which distro? Debian for example always keeps two kernels: the curent one and the one in use before that, which is what I prefer, never had to rely on more than one backup kernel.

    @GreenKnight23 @oong3Eepa1ae1tahJozoosuu I've never seen that behavior in Debian. Is that some different type of configuration?
