Memory Tagging Extension (MTE) is a mandatory hardware feature of Arm v9 CPUs that protects against memory safety bugs (with a slight runtime performance cost overhead) by providing detailed information about memory violations.

The Pixel 8 will feature Arm’s Memory Tagging Extensions (MTE), which can prevent some memory-based attacks. Other phones already support MTE in hardware but haven’t enabled it in Android. The Pixel 8 bootloader looks to be the first to implement this interface.

内存标记扩展 (MTE) 是 Arm v9 CPU 的一项强制性硬件功能，它通过提供有关内存违规的详细信息来防止内存安全错误（具有轻微的运行时性能成本开销）。

 

Pixel 8 将采用 Arm 的内存标记扩展 (MTE)，可以防止一些基于内存的攻击。其他手机已经在硬件上支持 MTE，但尚未在 Android 中启用。 Pixel 8 引导加载程序似乎是第一个实现此接口的。
