How to fix?

Upgrade Amazon-Linux:2 grub2-common to version 1:2.06-2.amzn2.0.1 or higher.
This issue was patched in ALAS2-2021-1684.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-common package and not the grub2-common package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

A flaw was found in the grub2-set-bootflag utility of grub2. A local attacker could run this utility under resource pressure (for example by setting RLIMIT), causing grub2 configuration files to be truncated and leaving the system unbootable on subsequent reboots.
