Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Privilege escalation in Intel AI Reference Models before v3.4.1 stems from a protection mechanism failure (CWE-693) within Ring 3 user-space applications, allowing unprivileged software to gain elevated access when a privileged user is passively present under specific deployment conditions. The vulnerability carries full confidentiality, integrity, and availability impact on the vulnerable system, though scope is contained with no subsequent-system impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following to be simultaneously true: (1) local access to the target machine - remote exploitation is not possible per AV:L; (2) Intel AI Reference Models in a version prior to v3.4.1 must be installed and running; (3) a privileged user must be present and performing passive interaction on the system - the description explicitly states 'requires passive user interaction' from a privileged user, which is the PR:H/UI:P nexus; and (4) specific attack requirements (AT:P) must be met - the description notes these are present 'without special internal knowledge,' meaning conditions are circumstantial rather than requiring insider information. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.4 (Medium) accurately reflects the multiple prerequisites constraining real-world exploitation: local access (AV:L), attack requirements present (AT:P), high privileges on the victim side (PR:H), and passive user interaction (UI:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is to upgrade Intel AI Reference Models to version v3.4.1 or later, as released by Intel and documented in advisory INTEL-SA-01432 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01432.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
