The update fixing the issue for Mageia 8 was released Wed, 26 Jan 2022 10:31 UTC (05:31 EST).

For anyone still running Mageia 7 (or older releases), the recommendation is …

As root run “chmod 0755 /usr/bin/pkexec”.
That will mean pkexec doesn’t work anymore. Running things like rpmdrake as a
regular user will not work. You must use an alternative approach to get root
privileges (open a terminal, use “su -” and then run rpmdrake or use sudo rpmdrake
if you’ve configured sudo).
