How to fix?

There is no fixed version for RHEL:8 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 RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections.
