First handset with MTE on the market

By Mark Brand, Google Project Zero Introduction It's finally time for me to fulfill a long-standing promise. Since I first heard about ARM's Memory Tagging Extensions, I've said to far too many people at this point to be able to back out… that I'd immediately switch to the first available device...

MTE As Implemented, Part 1: Implementation Testing

By Mark Brand, Project Zero Background In 2018, in the v8.5a version of the ARM architecture, ARM proposed a hardware implementation of tagged memory, referred to as MTE Memory Tagging Extensions. Through mid-2022 and early 2023, Project Zero had access to pre-production hardware implementing thi...

Summary: MTE As Implemented

By Mark Brand, Project Zero In mid-2022, Project Zero was provided with access to pre-production hardware implementing the ARM MTE specification. This blog post series is based on that review, and includes general conclusions about the effectiveness of MTE as implemented, specifically in the...

MTE As Implemented, Part 2: Mitigation Case Studies

By Mark Brand, Project Zero Background In 2018, in the v8.5a version of the ARM architecture, ARM proposed a hardware implementation of tagged memory, referred to as MTE Memory Tagging Extensions. In Part 1 we discussed testing the technical and implementation limitations of MTE on the hardware...
