It seems my Centos 7 repo “updates” is not up to date

I am trying to update my sudo package on Linux instances to remedy CVE-2021-3156. Some of Centos 7 boxes do not see required update sudo-1.8.23-10.el7_9.1.x86_64.rpm. I checked Centos 7 instances that successfully updated and their "Updates" repo stand at 1216 packages. The instances that fail to find update stand at 1174. I already ran command yum clean all but I am still getting the same count. Anybody know what is wrong and how to fix it?

Thanks in advance.
