Out-of-bounds read for some Intel(R) PROSet/Wireless WiFi Software within Ring 2: Device Drivers may allow an escalation of privilege. Network adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (low) impacts.
