CVE-2022-47454

Local WLAN service interruption via unchecked integer calculation

Published Mar 7, 2023 · Updated Mar 12, 2025

Integer overflow in Unisoc WLAN drivers for Android 10 through Android 12 allows local users to interrupt WLAN services. The WLAN driver performs an integer calculation without adequately checking its parameters, but Unisoc has not disclosed the affected function or exact failure mode. Exploitation requires high local privileges and user interaction; the documented consequence is limited to WLAN-service interruption.
