Nytro Posted May 26, 2018 Report Posted May 26, 2018 Tegra is NVIDIA’s embedded Android/Linux development platform featuring a powerful SOC. It is widely used in various types of devices such as smartphones, game consoles, and of course the automotive systems. Based on the Tegra-powered processors, the Tesla car boasts advanced infotainment and instrument cluster systems. So that during the last two years of Tesla security research, we gained lots of experience related to the Tegra platform. In this talk, we briefly analyze some known vulnerabilities related to Tegra, and then we will talk about the implementation of NVMAP, which is a unified memory management interface on Tegra. finally, we’ll share some interesting vulnerabilities we found in the NVMAP interface, such as denial of service, sensitive memory leak, and local privilege escalation. *** Sen Nie is a security researcher of Keen Lab.
