CVE-2023-30923

Local information disclosure via missing permission check

Published Jul 12, 2023 · Updated Dec 4, 2024

Information disclosure in the UNISOC Android messaging service allows local users to read messaging data through a missing permission check. The service omits an authorization check before exposing messaging information, but UNISOC has not disclosed the affected interface, operation, or data fields. Exploitation requires local access to a device with an affected UNISOC chipset running Android 10 through Android 13 and does not alter data or interrupt service.
