CVE-2022-38686

WLAN service interruption via missing parameter check

Published Feb 6, 2023 · Updated Mar 26, 2025

Improper parameter validation in UNISOC WLAN drivers for Android 10 and Android 11 allows local users to interrupt WLAN services. The kernel WLAN driver omits a parameter check, although UNISOC does not identify the affected function, parameter, or invalid state. Local access with high privileges is required, and the published description limits the consequence to denial of service despite a conflicting information-disclosure classification.
