Robustness of Llama3 and Codestral in Vulnerability Classification Under Obfuscation

Abstract

Abstract: This report synthesises findings from 10 peer-reviewed papers addressing the following research question: What is the impact of model size (e.g., 7B vs 70B) on the robustness of Llama3 and Codestral in classifying vulnerabilities in Big-Vul, measured by F1-score degradation under increasing levels of. 8 claims were extracted from source literature; 8 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.5/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research Question

What is the impact of model size (e.g., 7B vs 70B) on the robustness of Llama3 and Codestral in classifying vulnerabilities in Big-Vul, measured by F1-score degradation under increasing levels of synthetic obfuscation?

Verification Level

Descriptive public verification status only; aggregate claim counts are public, but individual claim records are not exposed here.

Quality Tier

Descriptive public triage only; this tier does not alter current publication or DOI behavior.

Quality Dimensions

Automated triage signals derived from public fields; not human peer review or independent validation.

Correction Record

Public corrections are additive records. Current status does not claim the synthesis is error-free.
