CVE-2022-47369

Local WLAN service interruption via unchecked parameters

Published Feb 6, 2023 · Updated Mar 26, 2025

Out-of-bounds write in the UNISOC WLAN driver on Android 10 through Android 12 allows local users to interrupt WLAN services. The driver fails to validate parameters before performing a memory write, allowing data to be written outside the intended bounds; the affected function and parameters are undisclosed. Exploitation requires high local privileges, and the documented operational consequence is interruption of WLAN services.
