Hello,
I am trying to update the kernel on my Debian 12 server (currently running version 6.1.147-1 / 6.1.0-38-amd64 with Plesk Obsidian 18.0.77).
My system currently reports that "all packages are up to date," but this kernel version is vulnerable to the CVE-2026-31431 ("Copy Fail") local privilege escalation exploit. I need to upgrade to a patched version (6.1.170-2 or higher).
Could you please verify if I need to adjust my /etc/apt/sources.list to include the correct Debian security repositories? I want to ensure that any changes I make will not conflict with the existing Plesk repositories or break the control panel.
Thank you for your assistance.
