Local privilege escalation via firewall type confusion
Published Sep 9, 2025 · Updated Sep 9, 2025
Type confusion in Microsoft Windows Defender Firewall Service allows local users in a specific group to elevate privileges. The service accesses a resource using an incompatible type, but Microsoft has not disclosed the affected code path, object, or attacker-controlled input. Exploitation requires local access, high privileges, and membership in a specific user group; success grants higher privileges without user interaction.
