Integer Overflow in GPU Driver Leads to OOB Write

Executive Summary

This vulnerability involves a non-privileged user running software that makes GPU system calls. When mapping a GPU buffer larger than 4GB, an integer overflow occurs, corrupting the array length. This can lead to out-of-bounds writes to GPU buffers.
