CVE-2024-38191

SYSTEM privilege escalation via kernel race condition

Published Aug 13, 2024 · Updated Jul 10, 2025

Privilege escalation in the Microsoft Windows Kernel Streaming Service Driver allows local users to obtain SYSTEM privileges through a race condition. The driver improperly synchronizes concurrent access to a shared kernel resource, but Microsoft has not disclosed the specific routine or resource involved. Exploitation requires local low-privilege access and successful timing of the race; compromise grants control at SYSTEM level.
