Yesterday Red Hat released an updated grub2 errata to resolve a CVE. You can find more details about this here:

While we have no CVE SLAs for CentOS, I thought it would be worthwhile to point to this given that grub and boothole have been hot topics recently. The sources for this fix are available in git.centos.org for CentOS Stream 8, and a new build has been completed.

https://git.centos.org/rpms/grub2/commits/c8s https://koji.mbox.centos.org/koji/buildinfo?buildID=16717

For those of you that also use RHEL, the CentOS Stream changes will land in a future RHEL minor release. Testing and feedback in any case is always welcome.

Thanks to the CentOS team for getting this turned around very quickly.
