| Confidentiality Integrity Availability Access Control | Modify Memory, Read Memory, DoS: Resource Consumption (Other), Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity, Quality Degradation 注記：If the decoding of an untrusted agent's identifier produces the security identifier of a trusted agent, then the untrusted agent can gain unauthorized access to the asset. | High |
潜在的な緩和策
Phases : Architecture and DesignSecurity identifier decoders must be reviewed for design consistency and common weaknesses.
Phases : Implementation
Access and programming flows must be tested in pre-silicon and post-silicon testing in order to check for this weakness.
脆弱性マッピングノート
理由 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
