CVE-2026-21400: Escalation of Privilege in 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.
AI Analysis
Technical Summary
This vulnerability involves a failure in protection mechanisms within Intel(R) AI Reference Models prior to v3.4.1, specifically affecting user applications operating in Ring 3. It allows an adversary with unprivileged software combined with a privileged user to escalate privileges through a low complexity local attack requiring only passive user interaction. The CVSS 4.0 score is 5.4 (medium), reflecting high impact on confidentiality, integrity, and availability within the vulnerable system context but no broader system impact. No vendor advisory or patch information is provided, and no known exploits are reported in the wild.
Potential Impact
The vulnerability can lead to escalation of privilege, potentially compromising the confidentiality, integrity, and availability of the vulnerable Intel AI Reference Model environment at a high level. However, it does not result in further impacts beyond the immediate system context. The attack requires local access, a privileged user context, and passive user interaction, with low attack complexity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation details are provided at this time.
