Multiple MediaTek chip wlan local privilege elevation vulnerabilities

MediaTek Inc. is the world’s fourth largest fab semiconductor company and a market leader in mobile devices, smart home applications, wireless connectivity technologies and IoT products, with approximately 1.5 billion devices a year with MediaTek chips built into them available around the world. Several MediaTek chips have a local elevation of privilege vulnerability, which stems from the lack of boundary checking in wlan, resulting in the ability to write out of bounds, which can be exploited by attackers for local elevation of privilege.
