Backdoor with root access found from OnePlus phones

All modern mobile phones have a baseband processor with root backdoor. OnePlus is only remarkable for having a second one.

Reference, or explanation?

If it has GSM/LTE/CDMA/etc baseband processor with closed implementation, assume it has remote root backdoor. Samsung has already been caught.

osmocombb tried to solve this. That project is essentially dead.

Librem 5 is a partial solution because the baseband has no access to the system.

Still has DMA, no?

No, the baseband radio will not be connected to the SoC via DMA.

They are proposing to use an external baseband with a USB or UART interface to the main SoC and a kill switch.
