Ah. I believe pretty much every safe language on the planet constantly has bugs in the implementation that can be exploited to cause unsafety. Sometimes they even get CVEs, e.g. in JavaScript VMs.
I don't do Javascript, but any self-respecting language which calls itself safe is actually safe. I worked for decades in actually memory and type safe languages, and never ever heard of a memory or type safety bug.
Just not the cheaters: Rust, Java (until recently), and of course Javascript with its unsafe implementations.
Memory safety bug in a proper lisp? Unheard of, unless you break the GC or do wrong FFI calls.
