I don’t think I understand what’s going on here. If I’m root on my machine then I should already have access to all the memory, so how does this matter?
It’s because even as root you don’t have access to all addresses.

You don’t have the access to Intel ME and AMD PSP by default. This hack can give you the read and write access.
