CVE-2026-20728

Privilege escalation via undisclosed protection failure

Published Aug 11, 2026 · Updated Aug 11, 2026

Protection mechanism failure in Intel Extension for TensorFlow before 2.15.0.3 allows local users with high privileges to escalate privileges. Intel identifies the affected locus only as Ring 3 user applications and has not published the failed protection or the operation that bypasses it. Exploitation requires local access, high privileges, attack requirements to be present, and passive user interaction; successful use compromises host confidentiality, integrity, and availability without reported subsequent-system impact.
