CVE-2022-38689

Local information disclosure via missing permission check

Published Oct 14, 2022 · Updated May 15, 2025

Missing authorization in the telephony service on UNISOC chipsets running Android 10 through 12 allows local users to read protected information. The service processes a local request without the required permission check, but UNISOC has not disclosed the request interface or data exposed. A local process with no additional execution privileges can reach the flaw; the published impact is limited to confidentiality, with no integrity or availability effect.
