CVE-2023-36046

Local authentication interruption via undisclosed link following

Published Nov 14, 2023 · Updated Oct 8, 2025

Denial of service in Microsoft Windows Authentication allows local users to interrupt authentication services via unspecified vectors. Microsoft maps the flaw to link following but does not disclose the affected file, function, link-resolution operation, or attacker-controlled input. Local low-privileged access is required; public records identify authentication disruption but do not describe the separately scored integrity impact.
