You can, though it's much harder than in C or C++ or unsafe Rust for this to be exploitable. A data race on an interface value can give you a corrupted interface value, overwriting the vtable with struct contents. This can happen to lead to arbitrary code execution if you're unlucky enough, though in most cases it would be a SIGSEGV. It's also very hard for an attacker to craft a payload that can be guaranteed to reach this, though with a microservixe architecture with automatic restarts of failed services, they might get a lot of tries.
