CVE-2022-47328

Local information disclosure via missing permission check

Published Feb 6, 2023 · Updated Mar 26, 2025

Information disclosure in the WLAN driver for UNISOC chipsets on Android 10 through Android 12 allows local users to read sensitive data. The driver omits a permission check before exposing unspecified WLAN information, but UNISOC has not identified the affected operation or data. Exploitation requires local access, high privileges, and high-complexity conditions; the reported consequence is limited to disclosure.
