Couldn't find anything of interest today either... My idea is that there's a bounds check that isn't done for some reason:
I'm pretty sure we can exclude the hypothesis that says that the increment value for the angle is incorrect because this number is not in function of the total step count, so it would probably make the angle value overflow whichever its value is. I also thought it could be number with which the angle value is multiplied by to convert the angle value to a [0, 4096] range, but this couldn't be the case since the step value is 1 and the counter would keep going over the limit value anyways. So, I'll keep investigating on this tomorrow. |
