Highlights

3. Improve linux-examples-fus

Update the examples to the new linux version.

4. New CVE Tracker Tool fs-cve-tracker

The F&S CVE Tracker Tool can help you to keep track of the current CVE status of your yocto image. It will launch a local version of Dependency Track and upload the SBOM of your Yocto Build to it. Dependency Track will scan your SBOM for vulnerabilities, which can be downloaded in VEX format. The F&S CVE Tracker Tool can also be used to improve your VEX file by marking already fixed CVEs or sorting out CVEs which affect components that are not in your build configuration.

You can also use Dependency Track to audit the remaining CVEs an generate Audit Reports for your documentation.

For a quick start you can run the following command after your Yocto Build has finished:

Code

./setup-yoto --cve-tracker

This command will install Dependency Track to your system, upload the SBOM from your build and improve your vulnerabilities scan to sort out as many false positives as possible.

Please note that this may take a while on first run.

Known Issues

No Bluetooth support for PCore8ULP rev 1.20 and higher in Linux-BSP.
