alt Hacker NewsHow many devices/operating systems even use memory tagging? iOS, macOS and GrapheneOS, I think that's it? And iOS/macOS only use it for the kernel, a subset of system processes, and I think applications can opt in to it.

We are moving way to slowly adopting hardware mitigations and memory-safe languages.
There's some positive news from the GrapheneOS devs on Pixel 11 in the past week that's worth reading up on. The MTE hardware feature is still there, they're just not sure why Google disabled it
