PrimSynth: An Agentic Framework for Autonomous Linux Kernel Exploit Synthesis
PrimSynth is a novel multi-agent, closed-loop framework designed to automate the synthesis of complex exploit chains for Linux kernel vulnerabilities. By bridging the conceptual gap between high-level exploitation objectives and low-level technical primitives, the system treats exploitation as a formal synthesis problem rather than simple pattern matching. It utilizes a multi-agent architecture to discover, validate, and upgrade exploit primitives within a rebootable sandbox environment. Evaluating across 16 real-world CVEs, the framework demonstrated a 100% primitive extraction accuracy and a 61.3% Strategy Synthesis Rate (SSR) in fully autonomous scenarios. This represents a significant shift from executing existing Proof-of-Concepts (PoCs) to the autonomous generation of new exploitation code for unpatched or unknown vulnerabilities.
