JAZB VTT-008-v1.2: Autonomous Vulnerability Research and Kernel Privilege Escalation

JAZB VTT-008-v1.2 evaluates whether JAZB Framework Version 1.2 can govern legitimate autonomous vulnerability research that progresses from code analysis to intentional kernel privilege escalation without allowing technical capability to become unrestricted organizational Authority.

The exercise uses the publicly reported research surrounding CVE-2026-72018 and XBOW’s Linux kernel exploit-development campaign as its scenario basis. It distinguishes public vulnerability information, researcher-reported claims, fictional JAZB implementation assumptions, and simulated tabletop outcomes. It does not claim that XBOW implemented JAZB or that the assumed governance controls existed in the source research environment.

The central research question is whether an authorized security-research objective can remain bounded as an AI AGENT adopts more intrusive methods, acquires additional privileges, targets kernel credential state, achieves root, considers a second host outside the authorized Scope, and prepares external vulnerability disclosure.

Across sixteen injects, the exercise evaluates bounded delegation, method-aware Authority, effective-target validation, independent Actuation, high-risk isolation, context-sensitive Point Policy, Governance Escape Resistance, protected evidence, independent Border Authority, temporary Authority expiration, and material-change revalidation.

Final disposition: PASS / BOUNDED AUTHORITY MAINTAINED, WITH FINDINGS.

Under the stated simulated implementation assumptions, legitimate exploit development and root-level execution remain permissible within explicitly established purpose, Scope, target, method, effect, duration, and safeguards. Obtaining root does not authorize persistence, unrelated data access, lateral movement, governance interference, or external disclosure.

An unauthorized second target is denied. Attempted circumvention is treated as potential Governance Escape. External disclosure requires independent Border Authority, and a later transition to a more autonomous multi-agent research architecture requires reevaluation rather than inheriting prior authorization.

The exercise identifies no internal contradiction requiring correction to JAZB Framework Version 1.2. It records a future-review question concerning JAZB-RS-168, which recommends compensating isolation for authorized high-risk activity using SHOULD rather than MUST. The exercise establishes a case for further validation without concluding that a normative change is required.

Technical prevention claims remain conditional on the relevant consequential path being mediated by the assumed governance and enforcement architecture, or by equivalent reliably preventive controls. A correct governance decision alone does not establish technical prevention. Unmediated paths, insufficient evidence, and ineffective enforcement remain implementation limitations.

A successful VTT validates the tested scenario and stated conditions. It does not establish permanent assurance.
