CVE-2022-44426

Local WLAN service interruption via integer overflow

Published Jan 4, 2023 · Updated Apr 10, 2025

Integer overflow in UNISOC WLAN firmware allows local users to interrupt WLAN services through the WLAN driver. UNISOC attributes the overflow to a missing bounds check in the driver but has not disclosed the affected operation or input. Local access is required; no prior privileges or user interaction are required, and successful exploitation interrupts WLAN services.
