Local privilege escalation via mishandled kernel memory objects
Published Apr 15, 2020 · Updated Aug 4, 2024
Elevation of privilege in affected Microsoft Windows and Windows Server releases allows local users to execute code with elevated privileges. The Win32k kernel-mode driver improperly handles objects in memory, but Microsoft has not disclosed the specific object type, function, or invalid operation. A local low-privileged user must execute a crafted application; successful exploitation grants higher privileges and can compromise confidentiality, integrity, and availability.
