Published Dec 6, 2022 · Updated Apr 23, 2025

Out-of-bounds read in UNISOC WLAN firmware for Android 10 through Android 12 allows local users to interrupt WLAN services. The WLAN driver fails to verify a buffer boundary before reading data, permitting an out-of-bounds access. Exploitation requires local access and user interaction, and the reported consequence is limited to interruption of WLAN services.
