CVE-2022-21505

Publication date 19 July 2022

Last updated 30 August 2024

Ubuntu priority

Medium

Why this priority?

Kernel lockdown bypass when UEFI secure boot is disabled / unavailable and IMA appraisal is enabled.

From the Ubuntu Security Team

It was discovered that the Integrity Measurement Architecture (IMA) implementation in the Linux kernel did not properly enforce policy in certain conditions. A privileged attacker could use this to bypass Kernel lockdown restrictions.
