CVE-2022-38683

Local contacts-service crash via missing permission check

Published Jan 4, 2023 · Updated Apr 10, 2025

Missing authorization in Unisoc contacts service on affected chipsets allows local users to crash the service on Android 10 through Android 12. The contacts service omits an unspecified permission check; Unisoc has not disclosed the affected interface or operation that reaches the check. Local access is required; published assessments disagree on the additional gate, but report only a contacts-service crash.
