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

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

CWE-1220 Insufficient Granularity of Access Control

The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.
