CVE-2022-44431

Local service interruption via WLAN out-of-bounds write

Published Jan 4, 2023 · Updated Apr 10, 2025

Out-of-bounds write in Unisoc WLAN firmware on Android 10, Android 11, and Android 12 allows local users to interrupt WLAN services. The WLAN driver omits a bounds check before a write, but Unisoc has not disclosed the affected routine, input field, or buffer. Local access is required, and the published description identifies WLAN service interruption as the consequence.
