Authenticated service interruption via undisclosed LSASS flaw
Published Oct 11, 2022 · Updated Jan 2, 2025
Denial of service in Microsoft Windows LSASS allows remote authenticated users to interrupt authentication services via network requests. Microsoft has not published the malformed input, protocol operation, or LSASS code path that triggers the failure. Network access with low privileges is required; the documented impact is limited to loss of availability, without reported data access or modification.
