Turns out I have been updating wrong all this time! 🤦🏼

submitted by TheIPW to linux 72 points | 27 comments https://the.unknown-universe.co.uk/tech-stories/update-conundrum/ 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.
