Nvidia Tegra Chip Burst Vulnerabilities, Disaster Nintendo Switch

The flaw lies in the recovery mode of the Nvidia Tegra X1 chip. Because the BootRom program error causes the hacker to execute arbitrary program in the recovery mode, in other words, the device can not be repaired after the factory is out of the factory, but the hacker must actually access the device to exploit the loophole.
The ReSwitched team that specializes in Nintendo (Nintendo) Switch games to perform homemade software has announced a vulnerability this week called Fus e e Gel e e, which is a security vulnerability hidden in the Nvidia Tegra X1 chip of the Switch host's core, which will allow hackers to execute arbitrary programs and declare that they can not be mended after the host is out of the factory. .
According to the team's explanation, the vulnerability exists in Tegra's Tegra Recovery Mode, which is caused by BootRom program errors and allows hackers to execute arbitrary programs when they enter the recovery mode. This means that the vulnerability must be exploited when the Switch host connects to the USB cable.
For gamers, the biggest advantage of the vulnerability is to back up the game, while another Team Xecuter, which specializes in various game hosts, has planned to launch a chip that exploits the related vulnerabilities.
Kate Temkin, a hardware engineer of the ReSwitched team, said that the Fus e e Gel e e vulnerability could not only affect Switch or X1, and could affect other devices using Nvidia Tegra X1, or more of the impact chips. The team has already submitted the details to the Nintendo and other industries, which would not have been open until June, but in order to avoid it A particular evil organization benefits from it and decides to announce it sooner.
The ReSwitched team stressed that their dismantling Switch games hosts only to use homemade software does not support any form of piracy, but Team Xecuter is a business team that specializes in various game hosts, making the outside guess that ReSwitched is intended to reverse Team Xecuter.
Temkin also warns that related vulnerabilities affect all versions of the Switch firmware, and because it is a program error in read - only BootRom, it is almost impossible to repair after the Switch is out of the factory.
Although the vulnerability can also affect Nvidia Tegra X1 devices outside Switch, equipment manufacturers say that hackers need to actually access devices to exploit vulnerabilities and reduce the threat of vulnerabilities, so they are not too worried.
