GrapheneOS Pixel 11 MTE support
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
GrapheneOS says Pixel 11 lacks MTE hardware security, blocking its port.
The project may skip Pixel 11 and focus on Motorola devices instead.
Background
GrapheneOS is a privacy-focused Android ROM that relies on ARM's Memory Tagging Extension (MTE) to mitigate memory corruption exploits. The project attempted a partial port to Google's Pixel 11 series but found MTE missing at software, firmware, and likely hardware levels. This prevents GrapheneOS from meeting its security standards, so it may drop support for the Pixel 11 and shift focus to an upcoming Motorola partnership.
How it unfolded
- Aug 12, 2026Google introduces the Pixel 11 series with Tensor G6, but launch material does not list MTE support.
- Aug 20, 2026Pixel 11 sales begin.
- Aug 28, 2026Android 17 QPR2 Beta 4 releases with Pixel 11 support; MTE is disabled in OS and firmware, but firmware adds MTE support back.
- Aug 30, 2026GrapheneOS announces it has only a partial Pixel 11 port and may skip the series due to missing MTE.
- Sep 1, 2026GrapheneOS reports Pixel 11 has bare minimum MTE hardware support, but performance is ruined and disabled in firmware; they are testing if it can be enabled.
Who’s saying what
- GrapheneOS
- MTE is non-negotiable for our security model; without it, we cannot support the Pixel 11 and may skip it entirely.
- Google has not publicly confirmed the MTE removal or the cost-saving claim.
- Analysts
- Pixel 11 includes other security features like post-quantum signatures and Titan M3, but these do not compensate for MTE loss according to GrapheneOS.
Still unverified
GrapheneOS's claim that Google removed MTE to save money is an inference, not confirmed by Google. The exact reason for MTE's absence (hardware errata vs. poor performance) is unknown.
