Also the article states it is found in intels chips too. So not really any better if they had stayed on that pathway either
I've just finished reading the article, it does not say this. It says Intel also has a DMP but that only Apple's version has the vulnerability.
Just reread it. You are indeed correct.
As I understand it, all DMPs of this type are subject to the vulnerability and so intel (and the newest m3) selectively disable it during cryptographic operations
Nope, dmp can treat value as pointer but doesn't need to. Intel doesn't, and because of that it's not vulnerable. But just in case they also provide a way to disable dmp
