CWE-366 Race Condition within a Thread Python version dependent

[BartyBoi1128]

Trying to demonstrate a non-compliant race condition, I'm having an issue where race conditions seem to not work on python versions that are higher than python3.10. Whatever example I seem to find online doesn't work on my version of python, which is python 3.11.4.

Not too sure what to do about this, but here is my code example demonstrating a race condition. This seems to work on Python 3.9, but not on anything that's version 3.10 or higher,

""" Non-compliant Code Example """
import logging
import sys
from threading import Thread
 
logging.basicConfig(level=logging.INFO)
 
 
class Number():
    """
    Multithreading incompatible class missing locks.
    Issue only occures with more then 1 million repetitions.
    """
    value = 0
    repeats = 1000000
    amount = 100
 
    def add(self):
        """Simulating hard work"""
        for _ in range(self.repeats):
            logging.debug("Number.add: id=%i int=%s size=%s", id(self.value), self.value, sys.getsizeof(self.value))
            self.value += self.amount
 
    def remove(self):
        """Simulating hard work"""
        for _ in range(self.repeats):
            self.value -= self.amount
 
 
if __name__ == "__main__":
    #####################
    # exploiting above code example
    #####################
    number = Number()
    logging.info("id=%i int=%s size=%s", id(number.value), number.value, sys.getsizeof(number.value))
    add = Thread(target=number.add)
    substract = Thread(target=number.remove)
    add.start()
    substract.start()
 
    logging.info('Waiting for threads to finish...')
    add.join()
    substract.join()
 
    logging.info("id=%i int=%s size=%s", id(number.value), number.value, sys.getsizeof(number.value))

Not sure how to proceed with CWE-366 at the moment.

We may need another example.
