1 minute read

During the Copy Fail security event, the Plesk security team published a very helpful guide (https://support.plesk.com/hc/en-us/articles/40124635047319-Vulnerability-CVE-2026-31431) detailing how to update the kernel for each Linux distribution.

Here are the commands for the distributions we use most frequently.

AlmaLinux

dnf clean metadata
dnf update 'kernel*'
reboot

Ubuntu

apt update
apt upgrade
reboot

Using sudo might be required.
