CVE-2022-47342

Local service interruption via unchecked array index

Published Feb 6, 2023 · Updated Mar 26, 2025

Array index underflow in UNISOC engineer-mode services on Android 10 and 11 allows local users to interrupt the service. The services accept a local operation without the required permission check, permitting an array index to underflow; UNISOC has not identified the affected function or input. No user interaction is required, and the documented consequence is limited to denial of service in the engineer-mode services.
