Ubuntu 20.04 LTS Security Update For "Dirty Pipe" Vulnerability

Canonical (the publishers of Ubuntu) have released a patch for the “Dirty Pipe” vulnerability (CVE-2022-0847) originally discovered by Max Kellermann.

This only affects Ubuntu 21.10 and 20.04 LTS systems running the Linux 5.13 kernel and could allow a local attacker to modify any file that could be opened for reading.

For all Ubuntu 20.04 LTS servers, the kernel update should happen automatically by Ubuntu and will require a reboot for the update to take effect. Please reach out to support if you have any questions.
