Local privilege escalation via Win32k object handling
Published Feb 11, 2020 · Updated Aug 4, 2024
An elevation of privilege flaw in Microsoft Windows allows local users to gain high privileges through the Win32k component. Win32k fails to properly handle objects in memory, enabling a crafted local application to cross the normal privilege boundary. Exploitation requires local authenticated access and can compromise confidentiality, integrity, and availability; the public record does not describe a remote attack path.
