CentOS - Jun 2021 - Security Updates not properly flagged

Hi,

I assumed that it's possible to install security updates with "yum
--security update".
On the centos-announce mailinglist and I have received several security updates
recently.
Most are not relevant for us but glib2 and kernel are two we would like to
address without updating the whole system.

Unfortunately both glib2 and kernel updates are filtered while running yum
--security update

This is the output:
 --> glib2-2.56.1-9.el7_9.x86_64 from updates removed (updateinfo)
 --> kernel-3.10.0-1160.31.1.el7.x86_64 from updates removed (updateinfo)   

There are probably more security updates which should be installed by yum
--security but those are the packages I am most interested in.

Please change as necessary to allow yum --security to work.

Many thanks.

Best Regards,
Thomas

CentOS does not provide the metadata to allow the --security flag to
work.

It doesn't provide it because that information from Redhat is
proprietary and not open source.
