final [GrapheneOS] 📱👁️‍🗨️ on Nostr: Next release for 9th generation Pixels will have further hardening with RANDSTRUCT ...

Next release for 9th generation Pixels will have further hardening with RANDSTRUCT enabled for the kernel with a deterministic seed (the commit timestamp).

RANDSTRUCT randomizes the order of data structures and function pointer tables at compilation based on a seed, so exploits need to be catered to specific seeds. We've made it deterministic to preserve #GrapheneOS reproducible builds by using the hash of the commit date as a seed so it changes the layouts with each base kernel change and we can make it per-device-model later too.

When other devices get Kernel 6.1 (the upstream is in testing) it can be possible for them to get it too.
