CVE-2023-30914

Local information disclosure via missing email authorization

Published Jun 6, 2023 · Updated Jan 8, 2025

Missing authorization in Unisoc Android 10, Android 11, and Android 12 email service allows local users to disclose protected information. The service fails to perform a required permission check before exposing data, but Unisoc has not disclosed the affected interface or data type. A local user can cross the authorization boundary without user interaction; published assessments disagree on whether prior privileges are required.
