Lifecycle Timeline
1DescriptionCVE.org
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. No active exploitation has been confirmed by CISA KEV and no public exploit code has been identified at time of analysis.
Technical ContextAI
The vulnerability resides in the Intel Extension for TensorFlow (ITEX), Intel's performance-optimized library that accelerates TensorFlow workloads on Intel CPUs and GPUs. The flaw is classified under CWE-693 (Protection Mechanism Failure), meaning the software either omits or incorrectly applies a defensive control - such as bounds enforcement, privilege separation, or memory isolation - within Ring 3 (user-space). Ring 3 is the least privileged CPU execution ring in x86 architecture; a failure there allows user-mode code to bypass expected application-layer protections. The CVSS 4.0 vector AV:L/AC:L/AT:P/PR:H/UI:P indicates local execution, specific attack preconditions (AT:P), and elevated privilege requirements, grounding the technical trigger in a privileged user-space context. Affected CPE: cpe:2.3:a:n/a:intel_extension_for_tensorflow_software:*:*:*:*:*:*:*:*.
RemediationAI
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). If an immediate upgrade is not feasible, consider restricting execution of ITEX workloads to the minimum required privilege level and auditing service accounts with elevated rights that invoke ITEX components. Preventing passive user interaction triggers - such as isolating the ITEX execution environment from untrusted inputs or shared session contexts - may reduce exposure, though these are compensating measures with limited assurance compared to patching. No side-effect data for version 2.15.0.3 was available in the provided intelligence.
