CVE-2022-39107

Local privilege escalation via missing permission check

Published Oct 14, 2022 · Updated May 15, 2025

Missing authorization in UNISOC Soundrecorder service on Android 10 through 12 allows local users to elevate privileges. The service omits a required permission check, but UNISOC has not disclosed the affected interface, function, permission, or privileged operation. The flaw requires local reachability but no additional execution privileges, and the resulting privilege gain is confined to the Soundrecorder service.
