Privilege escalation via incorrect per-user GameStream authorization
Published Dec 23, 2021 · Updated Aug 3, 2024
Incorrect authorization in GameStream in NVIDIA GeForce Experience before 3.24.0.126 allows local users to access protected resources. GameStream fails to enforce per-user access controls between accounts on the same device, extending access beyond its intended security authority. Successful exploitation requires low-privileged local access and user intervention and permits privilege escalation, data disclosure or tampering, and service interruption.
