CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
            def read(self, bytes):
                self.iterations -= 1
                if not self.iterations:
                    return b""

                return b"A" * bytes
