This post from 2022 was very interesting:
There are approximately 1.5 million total lines of Rust code in AOSP across new functionality and components [...] These are low-level components that require a systems language which otherwise would have been implemented in C++.
To date, there have been zero memory safety vulnerabilities discovered in Android’s Rust code.

The fact that rustc has bugs (which is what cve-rs exploit) doesn't invalidate that rust the language is memory safe.
