Local privilege escalation
Published Jan 10, 2023 · Updated Jan 1, 2025
Improper input validation in Microsoft Windows Overlay Filter allows local users to elevate privileges on affected Windows releases. Microsoft has not published the affected input, code path, or validation error within the filter. Exploitation requires existing low-privileged local access and grants control beyond that account, while the precise resulting privilege level remains undisclosed.
