CVE-2022-47327

Local information disclosure via missing permission check

Published Feb 6, 2023 · Updated Mar 25, 2025

Missing authorization in Unisoc WLAN drivers on Android 10 through Android 12 allows local users to read protected information. The driver omits a required permission check before exposing data, but Unisoc has not identified the affected interface, request path, or data returned. Exploitation requires local low-privileged access on a device using an affected Unisoc chipset; the reported consequence is disclosure only.
