M1ssing Register Access Controls Leak EL0 State

[prwnr]

My friend just sent me this website: https://m1racles.com/ (not sure if I can post this link here just like that) with quite a lot of information about a bug in M1 chip and I'm quite amazed that I didn't saw this topic here on macrumors, is this something that just came out? what do you think?

It is good that stuff like this surfaces but to quote his site:

So what's the real danger?

If you already have malware on your computer, that malware can communicate with other malware on your computer in an unexpected way.
Chances are it could communicate in plenty of expected ways anyway.

I’m not really worried by this vulnrability.

On a side note, that was a really funny read.

TLDR: This does not have any security impact unless your Mac is already compromised by something else.
