GrapheneOS project: pixel 11 no longer supports hardware memory tagging (MTE)
We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.
Summary
The GrapheneOS project has made progress on porting its system to the Pixel 11 series, but has hit a roadblock due to the absence of ARM hardware memory tagging support. This decision by Google to remove a key security feature raises concerns about the implications for device safety.
