Not really. There is a bunch of proprietary firmware running on those phones, which can be exploited with or without the help of the manufacturer.
- rollcat 11mo agoFirmware is not OS. Your machine is a distributed system. The firmware is what runs a specific node. Yes they usually have DMA, shared busses, etc. That's an implementation detail.
- fragmede 11mo agoAn implementation detail where TLAs could theoretically get root remotely? Seems like a bit more than a detail to be glossed over.
- rollcat 11mo agoFree firmware can have a security issue and root your device. A working IOMMU will stop both free- and non-feee firmware from rooting your device. These concepts are orthogonal.
- gf000 11mo agoShow me any device on earth that can run a browser that has no proprietary code whatsoever (including hardware) on it?
- SXX 11mo agoAFAIK older Talos Secure Workstation with Power CPUs was it. Everything open including CPU firmware. Not sure about smartphones though - they mostly struggle with a fact there are no truly open source baseband.
- Andromxda 11mo agoThere is no smartphone fully powered by open firmware. Also keep in mind that the hardware itself is proprietary too.
