CVE-2026-28707

Local privilege escalation

Published Aug 11, 2026 · Updated Aug 11, 2026

Protection mechanism failure in Intel LLM-on-Ray before 1.0 allows local users to elevate privileges in Ring 3 user applications. Intel identifies the affected locus only as Ring 3 user applications and has not disclosed which protection mechanism fails or what unsafe operation occurs. Exploitation requires a high-privileged local context, additional attack conditions, and passive user interaction; success compromises the vulnerable system's confidentiality, integrity, and availability.
