Protection mechanism failure for some Intel Extension for TensorFlow software before version 2.15.0.3 within Ring 3: User Applications may allow an escalation of privilege. System 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 Extension for TensorFlow software before version 2.15.0.3 stems from a protection mechanism failure (CWE-693) operating at Ring 3 - the CPU user-application privilege boundary. A system software adversary holding high privileges can exploit this failure under specific local attack conditions with passive user interaction to achieve full confidentiality, integrity, and availability compromise of the vulnerable system. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already possess high-privilege access (PR:H) on the local system - the CVSS 4.0 vector explicitly sets PR:H and AV:L, ruling out remote or unauthenticated attack. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.4 reflects substantial constraints: local access only (AV:L), attack requirements present (AT:P), high privileges required (PR:H), and passive user interaction (UI:P) - all of which meaningfully reduce real-world exploitability. … 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 remediation is to upgrade Intel Extension for TensorFlow software to version 2.15.0.3 or later, as confirmed by Intel advisory Intel-SA-01458 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01458.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
