CVE-2022-44446

Local WLAN service interruption via missing bounds check

Published Jan 4, 2023 · Updated Apr 10, 2025

Buffer over-read in Unisoc WLAN firmware on affected Android 10 through Android 12 chipsets allows local users to interrupt WLAN services. The WLAN driver fails to enforce a buffer boundary before reading data, producing an out-of-bounds firmware read. Local access and device privileges are required; the published consequence is limited to interruption of WLAN services.
