CVE-2025-31713

Local privilege escalation via engineer-mode command injection

Published Aug 18, 2025 · Updated Aug 18, 2025

Command injection in UNISOC chipsets running Mocor5/Android 8.1 allows local users to gain elevated privileges through engineer-mode input. The service places improperly validated input into a command context, but UNISOC has not disclosed the responsible handler, input field, or executed command. Exploitation requires local access to an affected device and no prior privileges or user interaction; successful injection can compromise device data and operation.
