vendor n/a Intel(R) AI Reference Models

Protection mechanism failure for some Intel(R) AI Reference Models before version v3.4.1 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.

    Detected

    Ring 3 内のバージョン v3.4.1 より前の一部の Intel(R) AI Reference Models における保護機構が失敗する問題：ユーザーアプリケーションが権限昇格を許す可能性があります。特権ユーザーと組み合わされた権限のないソフトウェア攻撃者は、低複雑度の攻撃を行うことで権限昇格が可能になる場合があります。この問題は、特別な内部知識を必要とせず攻撃要件が存在する場合に、ローカルアクセスを通じて発生し、受動的なユーザー操作を必要とします。潜在的な脆弱性は、脆弱なシステムの機密性（高）、完全性（高）、可用性（高）に影響を及ぼし、その結果、システムの機密性、完全性、可用性に深刻な影響を与える可能性があります。
