Overview

Description
An information disclosure vulnerability exists in the the way IOBit Advanced SystemCare Ultimate 14.2.0.220 driver handles Privileged I/O read requests.

The IN instruction can read two bytes from the given I/O device, potentially leaking sensitive device data to unprivileged users.
