Local privilege escalation via DatePickerFlyout use-after-free
Published Sep 9, 2025 · Updated Sep 9, 2025
Use-after-free in Microsoft Windows UI XAML Phone DatePickerFlyout allows local users to elevate privileges on affected systems. Microsoft has not disclosed which object is freed prematurely or the lifetime-management sequence that later dereferences it. Exploitation requires existing low-privileged local access and high-complexity conditions, and success crosses a security boundary to gain elevated privileges.
