Local privilege escalation via undisclosed integer overflow
Published Aug 13, 2024 · Updated Jul 10, 2025
Integer overflow in the Windows Cloud Files Mini Filter Driver allows local users with basic access to elevate privileges. Microsoft identifies the driver and CWE-190 but does not disclose the faulty calculation, attacker-controlled input, or affected function. Exploitation requires low privileges and no user interaction, and successful exploitation compromises host confidentiality, integrity, and availability.
