Previously, Mario Kart 7 on the 3DS was vulnerable to the vulnerability. Numerous Switch titles, including Mario Kart 8 Deluxe, Animal Crossing: New Horizons, Nintendo Switch Sports, and Splatoon 2 and 3, were also presumably affected. Nintendo appears to have patched all of those games to safeguard them against the vulnerability.
ENLBufferPwn is shown in action on Mario Kart 7 in a video shared by YouTuber PabloMK7 in December. It’s used to install modified firmware on the console in question. PabloMK7 stated on GitHub that it is “theoretically conceivable” to steal an account or credit card information and record a victim using the 3DS’s microphone and cameras.
