CVE-2023-30942

Local information disclosure via missing permission check

Published Jul 12, 2023 · Updated Dec 4, 2024

Information disclosure in UNISOC telephony service on listed chipsets allows local users to read sensitive data on Android 10 through 13. The service omits a required permission check before returning the data, but UNISOC has not disclosed the affected entry point or data type. A local process needs no execution privileges or user interaction, and the published impact is limited to confidentiality.
