How to fix?

There is no fixed version for RHEL:9 grub2-pc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-pc package and not the grub2-pc package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

GNU GRUB (aka GRUB2) through 2.12 does not use a constant-time algorithm for grub_crypto_memcmp and thus allows side-channel attacks.
