CVE-2022-47347

Local service interruption via array-index underflow

Published Feb 6, 2023 · Updated Mar 25, 2025

Array-index underflow in UNISOC engineermode services on Android 10 and 11 allows local users to interrupt the service. UNISOC attributes the underflow to a missing permission check but does not identify the affected function or operation. Local access is required and no user interaction is needed; published assessments disagree on whether low privileges are required.
