Summary
This vulnerability affects Microsoft Windows operating systems, including Windows 7, Windows 8.1, Windows 10, and several Windows Server editions. It could allow an attacker who already has access to a system to gain higher privileges than they should have, because the Win32k component mishandles objects in memory.
