For anyone else not knowing what MTE stands for:

> Memory safety bugs, which are errors in handling memory in native programming languages, are common code issues. They lead to security vulnerabilities as well as stability problems.

>Armv9 introduced the Arm Memory Tagging Extension (MTE), a hardware extension that allows you to catch use-after-free and buffer-overflow bugs in your native code.

To clarify, regarding the confusion: it was disabled , leading them to think it didn't outright exist. Why disabled? Well, its performance is apparently quite poor. But why? ...Apparently to save money.

The thread made it sound like it was more- that the actual release of pixel 11 did not have the firmware to support MTE, not that it was just disabled.

Is the thread wrong or did I misread it?

Boo. I was delighted by its introduction in pixel 8. I thought this was a resurgence of the old Google, actually giving a f about software, security and the end user.

iPhone 17 has it now. maybe Google's work here is done
