Some technical background on your observation. The mentioned VT is checking for the version provided by the OPENVAS_VERSION constant of the following GVM components:
major version
component
<= 9.0
openvas-libraries
= 10.0
openvas-scanner
>= 11.0
openvas
As you’re on the GVM 9.0 release shipped by Kali Linux this means:
Your openvas-libraries package wasn’t updated to version 9.0.3 yet to match the existing version 9.0.3 of the openvas package.
The version 9.0.3 of the openvas package isn’t actually a lower version like e.g. 9.0.1 and should have been received a version number like e.g. 9.0.1kali3.
In both cases please contact the maintainer of the Kali packages about this issue.
