Just curious, how relevant is MTE when considered a security feature? IIRC, last time i checked there were reports about extracting tag values so that maybe the access control enforced by the tags can be bypassed.

MTE is very important because its a measure against an entire, very important class of vulnerabilities, memory safety vulnerabilities.

Generations of MTE improve over time. The implementation of MTE used on a Pixel 8 for example has certain side channels which arent present in the MTE used on an iPhone 17. That being said, it being imperfect doesn't make it irrelevant.

Thanks, good to know it's still improving
