CVE-2022-38682

Local service interruption via missing permission check

Published Jan 4, 2023 · Updated Apr 10, 2025

Missing authorization in UNISOC contacts service on affected Android 10–12 chipsets allows local users to interrupt the service. The service processes a protected request without first checking the caller's permission; UNISOC has not disclosed the specific interface or operation. A locally executing caller with no additional execution privileges can make the contacts service unavailable, with no reported confidentiality or integrity impact.
