Google’s decision to use Rust for new law in Android in order to reduce memory- related excrescencies appears to be paying off. Memory safety vulnerabilities in Android have been further than halved – a corner that coincides with Google’s switch from C and C to the memory-safe programming language, Rust.
This is the first time that memory safety vulnerabilities aren’t the biggest order of security excrescencies, and comes a time after Google made Rust the dereliction for new law in the Android Open Source Project( AOSP).
Other memory-safe languages Google has used for Android include Java and Java-compatible Kotlin. C and C are still dominant languages in AOSP, but Android 13 is the first interpretation where utmost of the new law is from memory-safe languages. After Google espoused it for AOSP in April 2021, Rust now accounts for about 21 of new law. The Linux kernel design this time espoused Rust as the new sanctioned alternate language toC.

Android interpretation 10 from 2019 had 223 memory safety bugs, while Android 13 has 85 known memory safety issues.
Over that period, memory safety vulnerabilities have dropped from 76 down to 35 of Android’s total vulnerabilities, notes Android security software mastermind Jeffrey Vander Stoep. With this drop in memory safety vulnerabilities, Google is also seeing a decline in critical and ever exploitable excrescencies.

Vander Stoep notes that this change wasn’t driven by” heroics” – just inventors using the stylish tools for the job. The Android platoon plans to step up operation of Rust, although there are no plans to get relieve of C and C for its systems programming.
Still, I would say’ modesty’,” If I had to identify a single specific that makes this possible. There is a amenability within all situations of the Android platoon to say’ How can we do better?’ on with the fiber to follow through and make changes, including systemic changes,” he noted in a tweet.
” Humility needs to go both ways however. Rust does not break all problems, and there are areas where C/ C will continue to be the most practical option for development, at least for a while. That is OK.
” We will work on reducing that over time while continuing to gauge up our Rust operation and continuing to invest- in and emplace advancements to C/ C.”

Correlation does not equate to occasion, Vander Stoep notes, but the chance of memory safety security bugs – which dominate high- inflexibility bugs – does nearly match the languages used for new law.
Security tools like blacken have also made a big impact on memory safety bugs, says Google.
” We continue to invest in tools to ameliorate the safety of our C/ C. Over the once many releases we have introduced the Scudo hardened allocator, HWASAN, GWP- ASAN, and KFENCE on product Android bias. We have also increased our fuzzing content on our being law base. Vulnerabilities set up using these tools contributed both to forestallment of vulnerabilities in new law as well as vulnerabilities set up in old law that are included in the below evaluation. These are important tools, and critically important for our C/ C law. still, these alone don’t regard for the large shift in vulnerabilities that we are seeing, and other systems that have stationed these technologies haven’t seen a major shift in their vulnerability composition. We believe Android’s ongoing shift from memory-unsafe to memory-safe languages is a major factor,” writes Vander Stoep.
He goes on to note that in Android 13 there are1.5 million total lines of Rust law, representing about 21 of all new law. To date, Google has seen not a single memory safety vulnerability in Android’s Rust law.

” It demonstrates that Rust is fulfilling its willed purpose of precluding Android’s most common source of vulnerabilities. literal vulnerability viscosity is lesser than 1/ kLOC( 1 vulnerability per thousand lines of law) in numerous of Android’s C/ C factors(e.g. media, Bluetooth, NFC, etc). Grounded on this literal vulnerability viscosity, it’s likely that using Rust has formerly averted hundreds of vulnerabilities from reaching product,” Vander Stoep notes.

Google sees the move down from C/ C as grueling , but is pressing ahead with the design for Android. still, it isn’t moving to Rust for Chrome.
For Android, however, Google is enforcing userspace tackle abstraction layers( HALs) in Rust and adding support for Rust in Trusted Applications. It has also migrated virtual machine firmware in the Android Virtualization Framework to Rust. And with support for Rust in the Linux kernel interpretation6.1, Google is bringing memory safety to the kernel, starting with kernel motorists.
