TL;DR: Embedded C/C++ SBOMs diverge when scanners infer dependencies instead of observing the build, according to RunSafe Security. Product teams then inherit component lists that may not match what shipped, which weakens vulnerability triage and release attestation.
Editorial analysis by NHI Mgmt Group, based on content published by RunSafe Security: “How to Validate SBOM Accuracy for Embedded C/C++ Projects”.
Key questions
Q: Why do repository scans miss components in embedded software?
A: Repository scans miss components in embedded software because the source repository often does not contain every shipped binary, generated file, or vendor-supplied firmware image.
Q: What makes static libraries hard to capture in an SBOM?
A: Static libraries are hard to capture in an SBOM because their code is compiled directly into the final binary, so the original library boundary disappears.
Q: How should embedded teams generate SBOMs for C/C++ builds?
A: Embedded teams should generate SBOMs from the build process, not from repository snapshots alone.
Practitioner guidance
- Validate the SBOM generation method Confirm whether the tool observes the build, infers from source, or reconstructs from binaries, and reject outputs that cannot explain how the component list was produced.
- Test against a known build Use a controlled embedded project with static libraries, vendored code and conditional compilation, then check whether every expected component appears with precise version data.
- Bind SBOMs to release artifacts Require a cryptographic link between the SBOM and the exact firmware or binary that shipped so later investigations can verify the released build.
Bottom line: Embedded C/C++ SBOMs fail when they describe source repositories instead of released artifacts.

Artifact truth, not scan volume, is the real SBOM control: Embedded C/C++ forces practitioners to judge whether the record matches the shipped output, not whether a scanner produced a long inventory. Build-time evidence is the only reliable basis for that judgement when conditional compilation and static linkage change the software that actually runs. The practical conclusion is that SBOM governance should be evaluated on release fidelity, not component count.
A question worth separating out:
Q: What should teams do first when their SBOMs are inconsistent across tools?
A: Start by standardising the fields that must appear in every SBOM, then enforce one generation method in the build pipeline. If teams cannot trust what the record means, they cannot compare releases, automate vulnerability checks or use the SBOM as evidence in audit and incident workflows.
