The only difference is context. The scanner matched each CVE against the VEX file and suppressed every one that Docker assessed as not exploitable.\n\nThe packages are still there. Check the SBOM and you will see libc6, libsqlite3-0, and every other package from Step 1. Zero CVEs does not mean the packages were removed. It means each reported CVE has a documented reason why it does not apply to this product configuration. …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
