    Highlights

    Here are some highlights of this release.

    1. New Linux Kernel 6.6.119

    The Linux kernel is now based on 6.6.119

    2. New Yocto version 5.0.15 Scarthgap

    Updating poky to Version 5.0.15 Scarthgap. Updating other layers to their latest commits.

    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 consists of a script to generate an optimized SBOM and and a GUI to track CVEs.

    The F&S CVE Tracker scans your SBOM for vulnerabilities, which can be downloaded in VEX format. The tool can also be used to improve your VEX file by marking already fixed CVEs or filtering out CVEs that affect components not included in your build configuration.

    You can also use F&S CVE Tracker to audit the remaining CVEs and generate audit reports for your documentation.

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

    Code
    1. ./setup-yoto --cve-tracker

    This command will install F&S CVE Tracker 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.
