An elevation of privilege vulnerability exists when Windows improperly handles calls to Win32k.sys. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system.

To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.

The update addresses the vulnerability by correcting how Windows handles calls to Win32k.
