Local disclosure of sensitive data
Published Apr 13, 2021 · Updated Nov 19, 2024
Information disclosure in the Windows Overlay Filter in affected Microsoft Windows 10 and Windows Server releases allows local users to read sensitive data. Microsoft has not published the flawed operation, input path, or data exposed by the overlay-filter implementation. Exploitation requires low-privileged code execution on the target and needs no user interaction; the published impact is limited to confidentiality.
