Local privilege escalation via TOCTOU race
Published Oct 27, 2023 · Updated Sep 9, 2024
Privilege escalation in Lenovo Vantage SystemUpdate Plugin 2.0.0.212 and earlier allows local users to execute code with elevated privileges. The plugin checks a resource and later uses it after its state can change; Lenovo has not identified the resource, validation step, or privileged operation. Low-privileged local access is required, and successful exploitation runs attacker-controlled code in the plugin's elevated context.
