A flaw in an Nvidia chip used by the Switch, detailed today, lets power users inject code into the system and modify it however they choose.
The exploit, known as Fusée Gelée, was first hinted at by developer Kate Temkin a few months ago. She and others at ReSwitched worked to prove and document the exploit, sending it to Nvidia and Nintendo, among others.
Although responsible disclosure is to be applauded, it won’t make much difference here: this flaw isn’t the kind that can be fixed with a patch. Millions of Switches are vulnerable, permanently, to what amounts to a total jailbreak; only new ones with code tweaked at the factory will be immune.
That’s because the flaw is baked into the read-only memory of the Nvidia Tegra X1 used in the Switch and a few other devices. It’s in the “Boot and Power Management Processor” to be specific, where a misformed packet sent during a routine …read more
