Krynox Nexus
The Problem Developing secure custom Linux kernel modules for edge architectures is a high-stakes endeavor. A single memory safety flaw—such as a buffer overflow or a use-after-free vulnerability—can lead to privilege escalation or completely brick a device. Reviewing this low-level C/C++ code manually is tedious, dramatically slows down deployment cycles, and often misses hidden architectural vulnerabilities. The Solution: Krynox Nexus Krynox Nexus is a Zero-Trust DevSecOps pipeline built specifically for high-stakes kernel environments. It enforces a defense-in-depth architecture by integrating multi-tool static analysis (Clang, Cppcheck, Sparse) with intelligent orchestration. Every commit undergoes an automated build, deep architectural scan, and strict governance validation before it can be merged. How IBM Bob Powers the Pipeline We integrated IBM Bob not as a standard autocomplete tool, but as an autonomous "Lead Security Architect." When a developer pushes a new kernel module, Bob leverages full repository context to map dependencies against core kernel headers. It audits the codebase against a rigorous 27-point kernel configuration checklist tailored specifically for ARM64 edge devices. Most importantly, Bob performs active remediation. Instead of merely flagging a CWE-121 (Buffer Overflow), Bob explains the logical flaw and autonomously generates refactored, memory-safe code—for example, replacing unsafe bounds checks with proper kernel-space memdup_user() implementations. Impact & Unique Features Designed for systems engineers and embedded developers, the pipeline outputs natively to the GitHub Security tab via automated SARIF reports. Featuring a robust 7-job workflow, Krynox Nexus reduces audit times from hours to seconds, turning every developer into a security-first kernel engineer.
