With jitting runtimes like V8 often the root cause of the exploit is a logical error in code generation that leads to the sandboxed code to get a read/write gadget into memory outside the sandbox. Rewriting the jit in Rust might help eliminate those kinds of issues, but it's still entirely possible they would happen.
