Why I am getting an empty list when running yum updateinfo:

$ yum updateinfo
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile
 * base: centos.mirror.ate.info
 * epel: fedora.tu-chemnitz.de
 * extras: centos.mirror.ate.info
 * updates: ftp.rezopole.net
updateinfo summary done

However, when executing yum check-update, I see some available updates:

[root@instance /]# yum check-update

yum updateinfo lists the advisories for packages that can be updated. Am example output is:

Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile
 * base: centos.mirror.ate.info
 * epel: fedora.tu-chemnitz.de
 * extras: centos.mirror.ate.info
 * updates: ftp.rezopole.net
Updates Information Summary: available
   3 Security notice(s)
       1 Important Security notice(s)
       2 Moderate Security notice(s)
   1 Bugfix notice(s)
updateinfo summary done

On the other hand, yum check-update lists all the updates available for your packages. These you would typically upgrade to only if you need the extra functionality, not for security reasons.
