How to fix?

There is no fixed version for Centos:7 grub2-efi-ia32.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-efi-ia32 package and not the grub2-efi-ia32 package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.
