ModemSharedMemory¶

This page documents in more details the architecture of system on a chip and devices that have shared memory between the modem and the processor running Android. Since the modem runs (only) proprietary software, devices that doesn't have any mechanism that prevent the modem from taking control of the processor running Android are a grave concern for users freedom ans security.

This page focuses on that issue. Some Qualcomm System On a Chip that are affected by this issue also have other issues that aren't mentioned here but in the Qualcomm System On a Chip page.

Documenting the issue more in depth might allow us to understand if some devices with shared memory between the modem and the processor running Android might be able to be used safely.

System on a chip¶

This lists system on a chip that also Include a modem and have shared memory between the modem and the processor running Android, and the way the modem and the processor running Android are isolated or not.

Devices¶

This lists devices that have the modem and the processor running Android in separate chips and use shared memory between them, along with the way the processor running Android is isolated from the modem, or not.
