A list of the effected processors would've been nice, Wired.

The article links to this:

it may be possible for an attacker with ring 0 access to modify the configuration of System Management Mode (SMM) even when SMM Lock is enabled.

If attacker has a ring 0 access he can already screw you up any way he wants

that's all well and good, I was just responding to someone who wanted the list of affected products

It only mentions ring 0 access in your link, ergo they responded to your post because it was the most appropriate. At least that's how I see it.

The link includes 'CVE-2023-31315'

True. This does allow for persistent recurring infection post clean and cold boot.

Interesting flaw to keep an eye on.
