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

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'
