> You do realize that a full kernel vulnerability like this allows you to feed falsified information to SafetyNet?
Are you sure that's true? The whole reason why modern Safetynet/Play Integrity uses HSM data where possible is that you can't spoof that with root (without a microcode bug). It does not trust the running OS by design
I just tried GrapheneOS's https://attestation.app/ on a stock Pixel, and all of the OS version info shows in the "hardware verified" section
