Feedback-Driven Execution for LLM-Based Binary Analysis
Pith reviewed 2026-05-10 10:37 UTC · model grok-4.3
The pith
Structuring LLM binary analysis as a feedback-driven execution process with a dynamic forest of agents enables scalable vulnerability detection in firmware.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The paper claims that by replacing one-pass execution with a feedback-driven loop of reasoning, action, and observation, and by decomposing the work into a Dynamic Forest of Agents that coordinates parallel paths while limiting context size, LLM-based binary analysis becomes both scalable and more effective at finding vulnerabilities across diverse types.
What carries the argument
The Dynamic Forest of Agents (FoA), a decomposed execution model that dynamically coordinates parallel exploration while bounding per-agent context inside the reasoning-action-observation loop.
If this is right
- Analysis can adapt its path based on intermediate tool observations instead of a single static representation.
- Long-horizon multi-path exploration remains feasible without context overflow.
- Broader coverage of vulnerability types is achieved compared with prior one-pass LLM methods.
- Scalable application to thousands of real firmware binaries is possible while preserving usable precision.
Where Pith is reading between the lines
- The same interleaved loop could be applied to other code-analysis domains such as malware classification or protocol reverse engineering.
- Combining the agent forest with existing static-analysis tools might further improve the quality of observations fed back to the model.
- Adoption could lower the volume of manual expert review needed for initial screening of embedded-device firmware.
Load-bearing premise
The 3,457 firmware binaries and the vulnerability labels used to compute the 72.3 percent precision represent unbiased samples of real-world firmware without hidden selection effects or measurement biases.
What would settle it
An independent re-audit of the reported vulnerabilities that finds the true precision substantially below 72 percent, or a fresh run on a comparable but independently chosen set of firmware binaries that recovers far fewer unique affected binaries.

read the original abstract
Binary analysis increasingly relies on large language models (LLMs) to perform semantic reasoning over complex program behaviors. However, existing approaches largely adopt a one-pass execution paradigm, where reasoning operates over a fixed program representation constructed by static analysis tools. This formulation limits the ability to adapt exploration based on intermediate results and makes it difficult to sustain long-horizon, multi-path analysis under constrained context. We present FORGE, a system that rethinks LLM-based analysis as a feedback-driven execution process. FORGE interleaves reasoning and tool interaction through a reasoning-action-observation loop, enabling incremental exploration and evidence construction. To address the instability of long-horizon reasoning, we introduce a Dynamic Forest of Agents (FoA), a decomposed execution model that dynamically coordinates parallel exploration while bounding per-agent context. We evaluate FORGE on 3,457 real-world firmware binaries. FORGE identifies 1,274 vulnerabilities across 591 unique binaries, achieving 72.3% precision while covering a broader range of vulnerability types than prior approaches. These results demonstrate that structuring LLM-based analysis as a decomposed, feedback-driven execution system enables both scalable reasoning and high-quality outcomes in long-horizon tasks.

A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces FORGE, a system that reframes LLM-based binary analysis as a feedback-driven execution process using a reasoning-action-observation loop and a Dynamic Forest of Agents (FoA) to coordinate parallel exploration while bounding context. It evaluates the approach on 3,457 real-world firmware binaries, claiming identification of 1,274 vulnerabilities across 591 unique binaries at 72.3% precision with broader vulnerability-type coverage than prior methods.
Significance. If the evaluation methodology proves sound, the work could meaningfully advance LLM applications in security by showing how decomposed, adaptive agent coordination enables scalable long-horizon analysis on real firmware, addressing context-window and instability issues that limit one-pass static approaches. The scale of the binary corpus is a positive empirical contribution.
major comments (1)
- [Evaluation] Evaluation section (and abstract): The central performance claim of 72.3% precision on 1,274 vulnerabilities lacks any description of how ground truth was established, how false positives were measured, what labeling criteria or oracles (e.g., CVE matching, dynamic confirmation, expert review) were used, or whether post-hoc filtering occurred. Firmware binaries have no obvious oracles, so this omission makes the precision metric and the broader-coverage claim unverifiable and incomparable to prior work.
Simulated Author's Rebuttal
We thank the referee for their constructive feedback and for recognizing the potential significance of our work in advancing scalable LLM-based binary analysis. We address the major comment below and will revise the manuscript to improve transparency in the evaluation.

Authors: We agree that the manuscript does not provide sufficient detail on how ground truth was established or how the 72.3% precision was computed. This is a valid and important observation, as the lack of obvious oracles in firmware binaries makes such transparency necessary for verification and comparison to prior work. In the current version, the Evaluation section reports the aggregate results and claims but omits the required methodological description. We will revise the paper by adding a dedicated subsection in the Evaluation section (and updating the abstract for consistency) that fully describes the ground truth process. This will include the labeling criteria, the specific oracles and verification steps used (covering examples such as CVE matching, dynamic confirmation, and expert review), the approach to measuring false positives, and explicit confirmation that no post-hoc filtering occurred. These additions will render the precision metric and broader-coverage claim verifiable without changing the reported numbers. revision: yes
Circularity Check
No circularity: empirical results independent of any derivation chain
full rationale
The paper describes FORGE as a feedback-driven LLM analysis system using a reasoning-action-observation loop and Dynamic Forest of Agents, then reports empirical outcomes on 3,457 firmware binaries (1,274 vulnerabilities at 72.3% precision). No equations, fitted parameters, self-definitional constructs, or load-bearing self-citations appear in the abstract or described claims. The central results are presented as direct measurements from evaluation rather than quantities derived from or equivalent to the authors' inputs by construction. This is a standard systems-evaluation paper whose claims do not reduce to the listed circularity patterns.
