A new set of critical vulnerabilities have been disclosed in the Realtek RTL8170C Wi-Fi module. An adversary could abuse the vulnerability to gain elevated privileges on a device and hijack wireless communications. The flaws affect all embedded and IoT devices that use the component to connect to Wi-fi networks. The vulnerabilities follow an earlier analysis in February that found similar weaknesses in the RTL 8195A Wi-FI module. The company recommends using a “strong, private WPA2 passphrase” to prevent exploitation.
