Hello everyone, I write here because I think there’s a bug in the reports: in this example GVM found a vulnerability, but doubled it because for it that ip has two different hostnames, the report in question is only one (there are no other reports) and this problem occurs very often.
In the end it seems this host has 2 vulnerabilities when instead it’s only one, as if it does not understand that the ip and the mac address are the same … and sees it as 2 different hosts (in my opinion an error)
Here the example

Same OID
