Rust in Android: move fast and fix things

Google's Android security post reports that adopting Rust across the Android platform has sharply reduced memory-safety vulnerability density (an estimated >1000x reduction versus C/C++), improved development metrics (lower rollback rate, faster code review), and helped avoid shipping a Rust-based memory-safety issue: a near-miss linear buffer overflow in CrabbyAVIF (CVE-2025-48530) that was fixed pre-release and was non-exploitable on devices using the Scudo allocator; the post also describes follow-on actions including improved crash signals, unsafe-Rust training, and broader Rust rollout to kernel, firmware, and apps.
