Yes.
- “Windows Defender” is the service
- the discussion was about how Defender might have “root” access but Linux services have CVEs too.
The reason Defender has elevated access is precisely because it needs to do stuff like hook into file system events and scan files irrespective of their underlying ACLs.
So it’s not the same as desktop anpplication exploit that would be running as the same user/group as the person logged in. And it’s also not the same as any other type of service, be that a RDBMS, web server, IRC server, nor any other type of server you might think off.
In fact this is true for both Windows AND Linux. Your average service will not have access to read user files and desktop applications are not services running as root.
I get you’re trying to make a balanced argument. And I do agree that Linux has had a great many poorly thought out design decisions (and even more problems inherent from its POSIX lineage). But the specific arguments you’re making in this thread are just misinformed and misunderstand how these operating systems work.
