Rust still has memory related bugs

[–] dragonfly4933@lemmy.dbzer0.com 7 points 1 day ago (1 children)

This is correct, but not what most people think. For example, memory leaks could be considered bugs and it is easy to leak memory memory in safe rust on purpose.

Memory leaks are usually not disastrous for security, mostly an issue for availability, sometimes.

[–] Zangoose@lemmy.world 1 points 20 hours ago

I think a lot of the confusion comes from the ambiguity of the phrase "memory leak." Rust is designed around preventing insecure memory access (accessing out of bounds for an array, use-after-free, etc.) and devs call that a memory leak. But another form of memory leak is just not freeing up memory when its no longer needed (e.g. continuously pushing a bunch of things to a global vector and never clearing it). That is more of a fundamental program design issue that rust can't do anything about. (and really, neither could any turing complete language)
