Appendix

• Testbed specifications (hardware, OS, driver versions).
• Benchmark raw data summaries.
• Snippets of diffs and validation layer logs (redacted to avoid disclosing exploit details).
• Repro steps for benign tests (how to run benchmarks and validation layers).

• You updated your graphics driver (newer drivers bundle the latest Vulkan runtime)

• Do not delete it from System32.
• If suspicious, upload the file to VirusTotal — but first check its digital signature (Properties → Digital Signatures → should be Microsoft Windows or GPU vendor).

Background

• Brief overview of Vulkan architecture (loader, ICDs, validation layers, conformance).
• Role of "Vulkan Run Time Libraries" (distribution by GPU vendors, Windows integration).
• Prior work on runtime regressions, driver bugs, and security issues.
