CWE-1189: Improper Isolation of Shared Resources on System-on-a-Chip (SoC)

ID CWE-1189

Abstraction Base

Structure Simple

Status Stable

Number of CVEs 2

The System-On-a-Chip (SoC) does not properly isolate shared resources between trusted and untrusted agents.

A System-On-a-Chip (SoC) has a lot of functionality, but it may have a limited number of pins or pads. A pin can only perform one function at a time. However, it can be configured to perform multiple different functions. This technique is called pin multiplexing. Similarly, several resources on the chip may be shared to multiplex and support different features or functions. When such resources are shared between trusted and untrusted agents, untrusted agents may be able to access the assets intended to be accessed only by the trusted agents.
