System crash via NULL pointer dereference
Published Oct 8, 2024 · Updated Aug 19, 2026
Denial of service in the Microsoft Windows Kernel allows local users to crash an affected system after required user interaction. Microsoft identifies a NULL pointer dereference but has not disclosed the affected kernel locus or the untrusted operation that reaches it. Exploitation requires local low-privileged access and user interaction, and the documented consequence is loss of availability rather than data disclosure or modification.
