Memory-Safe Code Adoption Has Made Android Safer

Google reports a sharp decline in Android memory-related vulnerabilities driven by its Secure-by-Design strategy that prioritizes memory-safe languages such as Rust for new code. Memory-safety issues fell from 76% of Android vulnerabilities in 2019 to 24% today, with an estimated 36 memory-related flaws in 2024; the company emphasizes interoperability, gradual migration (since Android 12/13), tooling for safer C/C++ maintenance, and notes that older code shows lower vulnerability density compared to newly written code.
