SYSTEM privilege escalation via out-of-bounds read
Published Aug 13, 2024 · Updated Jul 10, 2025
An out-of-bounds read in the Microsoft Windows Kernel Streaming WOW Thunk Service Driver allows local users to gain SYSTEM privileges. Microsoft identifies the driver and weakness class but has not published the affected routine, attacker-controlled input, or exact invalid read operation. Exploitation requires prior low-privilege local access and permits execution in the SYSTEM security context.
