Mind the Gap: How SBOM Specification Ambiguities Lead to Divergent Software Bills of Materials. An Empirical Tool Study

Empirical study finds SBOM generators produce materially different outputs for identical software due to specification gaps—a direct compliance risk as the CRA's December 2027 deadline approaches.

arXiv:2609.19920v1 Announce Type: new Abstract: Software Bill of Materials (SBOMs) will become mandatory starting in December 2027 under the European Cyber Resilience Act (CRA) [8]. Although previous studies have highlighted significant differences among SBOM generators, the reasons for these discrepancies remain unknown, as does whether they stem from implementation errors or deliberate design choices. In this paper, we evaluate three widely used SBOM generators across more than 3,000 JavaScr

Editorial Analysis

Why it matters

The CRA will mandate SBOMs across the EU; if specification ambiguities are not resolved, enterprises risk non-compliance and unreliable supply-chain visibility despite tooling investment.

What to do

Benchmark multiple SBOM generators against critical products now and feed divergence reports into your CRA readiness programme.

Board brief

Research shows current SBOM tooling produces inconsistent results, posing a compliance risk under the EU Cyber Resilience Act's upcoming mandate.
