CVE-2022-47487

Local service interruption via unchecked thermal-service write

Published May 9, 2023 · Updated Jan 28, 2025

Classic buffer overflow in Unisoc thermal service on Android 10 through Android 13 allows local users to interrupt service. The service writes past a buffer because it fails to check the input size against the destination bounds; Unisoc has not disclosed the affected function. Local access and user interaction are required under Unisoc's assessment, and the documented consequence is limited to denial of service with an undisclosed failure mode.
