CVE-2022-44429

Local WLAN service interruption via heap overflow

Published Jan 4, 2023 · Updated Apr 10, 2025

Heap overflow in UNISOC WLAN firmware on chipsets running Android 10 through Android 12 allows local users to interrupt WLAN services. The WLAN driver performs a heap write without enforcing a bounds check; UNISOC has not published the affected function or input path. NVD and CISA require local low-privileged access, while the vendor vector lists no privileges; the reported consequence is limited to WLAN-service interruption.
