Local privilege escalation via Push Notifications type confusion
Published Aug 12, 2025 · Updated Feb 26, 2026
Type confusion in Microsoft Windows Push Notifications allows local users to elevate privileges on affected Windows builds. Microsoft identifies incompatible-type resource access in the Push Notifications component but has not disclosed the specific object, function, or untrusted input that triggers the confusion. A user must already hold local low-privilege access; successful exploitation grants higher privileges and can compromise confidentiality, integrity, and availability.
