Multiple MediaTek chip sensorhub 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 worldwide. Several MediaTek chips have a local elevation of privilege vulnerability, which stems from incorrect buffer size calculation in sensorhub and can be exploited by attackers for local elevation of privilege.
