CVE-2022-38680

WLAN service interruption via unchecked integer parameters

Published Feb 6, 2023 · Updated Mar 26, 2025

Integer overflow in the WLAN driver for Unisoc Android 10 through 12 chipsets allows local users to interrupt WLAN services. The driver fails to validate unspecified parameters before integer processing, but Unisoc has not disclosed the affected function or data path. Local high-privileged access is required; exploitation interrupts WLAN services, with no vendor-reported device-wide crash or persistent data loss.
