Nintendo’s Switch was hacked to run Linux in February, and now it’s clear that hackers could go further and run homebrew apps and games on the device. Eurogamer reports that two exploits have been detailed this week that allow hackers to exploit a hardware flaw in Nvidia’s Tegra X1 (that powers the Switch) and gain access to the Switch’s operating system. Nintendo cannot patch the hardware flaw without releasing a new version of the Switch, which means that at least 14 million devices are vulnerable.
It’s a jailbreak that’s similar to a “tethered” iPhone jailbreak, meaning it needs to be performed on every boot via USB. The hack doesn’t require a modchip, although it’s likely that third parties will now create Switch hardware mods to assist with the jailbreak.
