CVE-2023-42698

Local information disclosure via unchecked record writes

Published Dec 4, 2023 · Updated May 29, 2025

Information disclosure in the UNISOC omacp service on Android 11 through 13 chipset firmware allows local users to read app data. The service permits an app to write permission-usage records without checking whether the caller is authorized, exposing information associated with another app. Exploitation is local and requires no user interaction; published evidence limits the consequence to confidentiality loss.
