CVE-2022-47451

WLAN service interruption via unchecked integer arithmetic

Published Feb 6, 2023 · Updated Mar 25, 2025

Integer overflow in UNISOC WLAN drivers for Android 10 through Android 12 allows local users to interrupt WLAN services. The driver performs integer arithmetic without first validating supplied parameters; the public advisory does not identify the affected function or parameter. Exploitation requires local access and user interaction but no existing privileges, and the reported consequence is interruption of WLAN services rather than device shutdown.
