There's an urban legend that the baseband processor is an all governing, closed source backdoored bad actor in your phone. This may have been true for 2005 era

There's an urban legend that the baseband processor is an all governing, closed source backdoored bad actor in your phone. This may have been true for 2005 era dumbphones, but in reality your smartphone's radio is attached like a USB device is. In phones made in at least the last 10 years, it doesn't have a privileged position at all. I don't know why that legend keeps on being perpetuated.
There's a lot wrong with hardware openness on mobile devices, but closed bootloaders and radio firmwares are also true on most Linux laptops that can thrive nonetheless.
- b112 5y agoThe radio firmware can be remotely updated, without the OS being involved. EG, by carrier. It has direct access, without OS involvement, to many peripherals. At that stage, any further discussion (being able to read system ram or not, segregation or not) is moot, for, it's the ultimate in lack of trust.
- DCKing 5y agoYou're asserting more parts of the urban legend, but there's zero evidence this is true for anything that's not a mid 00s era dumbphone.
