Discussion of SMM interrupt code is irrelevant to the observation that installing Linux protects you from a Windows specific backdoor. That was not a claim that Linux provided safety against every possible backdoor. You seem to be trying to debunk a claim that no one made.
- vardump 10y agoI don't try to debunk anything. I think it's just silly to talk about some ACPI table payload, when there's a greater threat controlled by the same binary blob. SMM can do anything that ACPI payload could do and more. And we need to trust the same entity for its integrity. SMM is also operating system independent. It'll run no matter what operating system end user runs.
- ryao 10y agoIf you were not trying to debunk anything, then this was a very poor choice of words: > So, hypothetically speaking, say a laptop firmware has an SMM backdoor, how does using Linux bypass it in any way? Aside from that, good point.
