Local privilege escalation
Published Dec 10, 2025 · Updated Dec 10, 2025
Improper permissions in Lenovo Baiying Client before 4.1.0 allow local users to execute code with elevated privileges. Lenovo identifies incorrect default permissions as the cause but has not disclosed the affected file, service, or permission-setting operation. An authenticated local session with low privileges is required; successful exploitation grants control over the client’s data and execution context.
