SPIDER4TianoCore: Enhancing Patch-Propagation for the TianoCore UEFI Firmware Development Ecosystem
🤖 AI Summary
本文提出SPIDER4TianoCore工具，通过提供补丁状态证据来增强TianoCore UEFI固件开发中的补丁传播。
📝 Abstract
We propose and demonstrate SPIDER4TianoCore, a packaged Python command-line tool that provides integration-stage patch-status evidence for the TianoCore/UEFI firmware supply chain. Given an upstream pre-patch and post-patch pair and prepared downstream targets, the tool reports Vulnerable, Already Patched, Not Applicable, or Uncertain with supporting evidence for maintainer review. Our work is inspired by SPIDER's patch-propagation framing, but SPIDER4TianoCore does not itself prove that a patch is safe to propagate. We evaluate the engine on 20 prepared target/CVE pairs from eight public downstream EDK II repositories and two CVEs. The analyzers produce 10 high-confidence pre-patch matches and four high-confidence post-patch matches, conservatively abstain on six targets, and make no confidently wrong classifications relative to the recorded manual patch-state labels. These preliminary results demonstrate reproducible evidence generation for prepared targets rather than general downstream accuracy.
