Google is highlighting the use of the Rust programming language in Android’s low-level system code to limit the increase in memory-based security vulnerabilities in mobile operating systems.

In a post on the Google Security blog, members of the Android development team list efforts to detect, fix, and mitigate memory safety bugs. Despite their efforts, these vulnerabilities account for about 70% of Android’s high-severity security vulnerabilities.

Memory-safe languages ​​are the most cost-effective way to prevent memory bugs. In addition to memory-safe languages ​​such as Kotlin and Java, the Android Open Source Project (AOSP) has announced that it now supports the Rust programming language for developing the OS itself, “said Jeff Vander Stoep and Stephen Hines of the Android team. Is writing. ..

Memory management

Rust’s memory safety guarantees make Rust especially useful for low-level system programming. That’s why the state-of-the-art branch of the Linux kernel includes support for Rust.

Android developers use compatible languages ​​such as Java and Kotlin to describe the high-level parts of the OS, such as the user interface, while the low-level aspects, such as the kernel and drivers, are C and C. It is best written in ++.

However, these languages ​​are responsible for some important aspects to developers, such as memory management. This is one of the attractions of the language and developers welcome flexibility. However, improperly implemented memory management can lead to security issues such as buffer overflows and overreads, leading to the current plight of Android.

Google developers have said on their blog that they’ve been working behind the scenes to add support for Rust on Android for the past 18 months, and will probably showcase some of their early adopter projects in the coming months. I promise.
