NVD Description
Note: Versions mentioned in the description apply only to the upstream grub2-pc-modules package and not the grub2-pc-modules package as distributed by Centos.
See How to fix? for Centos:8 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.
