The biggest items on the graph are all out of bounds accesses, use-after-free and overflows. It is undeniable that memory safe languages help reducing vulnerabilities, we know for decades that memory corruption vulnerabilities are both the most common and the most severe in programs written in memory-unsafe languages.

Unsafe rust is also not turning off every safety feature, and it’s much better to have clear highlighted and isolated parts of code that are unsafe, which can be more easily reviewed and tested, compared to everything suffering from those problems.

I don’t think there is debate here, rewriting is a huge effort, but the fact that using C is prone to memory corruption vulnerabilities and memory-safe languages are better from that regard is a fact.
