A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a physically present attacker using a maliciously crafted USB device to trigger unbounded recursion in the driver's topology-parsing logic during device enumeration. Processing the crafted descriptor exhausts the kernel stack and causes a system crash (bugcheck), resulting in a denial of service. No authenticated user session is required.
