NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-tools-extra package and not the grub2-tools-extra package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

The GRUB2's shim_lock verifier allows non-kernel files to be loaded on shim-powered secure boot systems. Allowing such files to be loaded may lead to unverified code and modules to be loaded in GRUB2 breaking the secure boot trust-chain.
