Multiple MediaTek chip WLAN driver input validation error vulnerability

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 with MediaTek chips available worldwide each year. A number of MediaTek chips have an input validation error vulnerability in the WLAN driver, which stems from a lack of boundary checking in the WLAN driver and could lead to out-of-bounds writes. An attacker could exploit the vulnerability to perform local privilege elevation without requiring user interaction.
