Local service interruption via null-pointer dereference
Published Dec 9, 2025 · Updated Apr 16, 2026
Null-pointer dereference in the Microsoft Windows DirectX Graphics Kernel allows local users to interrupt service on affected builds. Microsoft has not disclosed the specific function or attacker-controlled input that reaches the invalid pointer operation. Exploitation requires local low-privilege access, needs no user interaction, and affects availability without reported data exposure or modification.
