CVE-2023-42712

Local information disclosure via unchecked permission-record writes

Published Dec 4, 2023 · Updated Aug 28, 2024

Missing authorization in the firewall service on Unisoc Android 11 and Android 12 chipsets allows local users to read app permission-usage records. The firewall service accepts a request to write an app's permission-usage record without enforcing the permission required for that operation. A low-privileged local app can reach the flaw without user interaction or additional execution privileges; the published impact is limited to confidentiality.
