Technical details
The vulnerability is a heap buffer overflow in USB host audio, video, and CDC class drivers that fails to properly validate device-supplied bNumEndpoints and bLength descriptor values. When a crafted malicious USB device provides specially constructed descriptors, endpoint entries are written past the bounds of a fixed-size epList array, corrupting adjacent heap memory. This enables arbitrary code execution or denial of service depending on exploit conditions.
