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.
