Why would you need a newer version? Note that security fixes get backported to the versions shipped by RHEL/CentOS.

Version 9.9.4 has vulnerabilities.
I would like to upgrade to fix.

No, it really doesn't have vulnerabilities.

Read the backports link that avij posted. Redhat take care of backporting all security fixes from the mainline code to their version.

If you have specific CVE numbers you're interested in the look at the output from rpm -q --changelog bind and grep for the CVE you're interested in. If nothing shows up then consult https://access.redhat.com/security/cve/cve-yyyy-nnnn to see what Redhat say about it - often if a CVE is not listed as fixed then there is a KB article that tells you why - for example "we don't enable that feature so the RHEL version is not vulnerable".

Also, if you don't find anything, make sure you are up to date by running yum update and see if there is a newer version pending which fixes it.
