CVE-2022-48234

FM service interruption via unchecked parameters

Published May 9, 2023 · Updated Jan 28, 2025

Stack overflow in the FM service on Unisoc chipsets running Android 10 through Android 13 allows local users to interrupt the service. The FM service handles parameters without a required validity check, causing a stack buffer to overflow; no function or parameter names are public. Exploitation requires high local privileges and no user interaction, and the reported consequence is limited to denial of service in the FM service.
