Upgrade Centos:8 grub2-efi-x64 to version 1:2.02-156.el8 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream grub2-efi-x64 package and not the grub2-efi-x64 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. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.
