This is about silicon. Undocumented instructions have just been found in it but they are not executable unless the ESP32’s firmware uses them. Firmware cannot be edited to use them unless you have an existing vulnerability such as physical access or insecure OTA in existing firmware (as far as researchers know).
Comment on Undocumented 'Backdoor' Found In Chinese Bluetooth Chip Used By a Billion Devices.
secret300@lemmy.sdf.org 3 weeks agoI 100% believe firmware should be open source no question about it. There’s so many devices out there especially phones and iot devices that just become e-waste because you can’t do anything with it once it’s not supported if it was open source and documented in some way then it could be used. I have like five cheap phones that I got because they were so cheap but once they lost support they’ve become completely useless even though they still work.

But then big companies wouldn’t be able to keep milking the consumer via planned obsolescence. Won’t somebody think of the shareholders?
