CVE-2023-42645

Local app information disclosure via unchecked records

Published Nov 1, 2023 · Updated Sep 5, 2024

Information disclosure in the SIM service on UNISOC T760, T770, T820, and S8000 Android 11 devices allows local users to disclose app information. The service permits permission-usage records to be written for an app without performing the required permission check. Exploitation requires local access but no additional execution privileges, and UNISOC has not disclosed which app information becomes visible.
