This is an example of an arbitrary right. Um this part is going to be inside IOCTL code. This is from a driver and you see that the mem copy is copying the system buffer. So basically what is coming from the ioctl from the user control and then it's seted there and then you have control of the file path and the len. So that's uh that's a
