Local disclosure of protected data
Published Oct 13, 2021 · Updated Aug 4, 2024
Information disclosure in the Windows Bind Filter Driver allows local users on affected Windows 10, 11, and Server releases to read protected data. Microsoft has not disclosed the faulty Bind Filter Driver routine or the operation that exposes data. Exploitation requires low-privileged local access; the published assessment limits impact to confidentiality, with no integrity or availability loss.
