This update corrects flaws in the following subsystems: - Network traffic control; (CVE-2025-38350, CVE-2025-37752, CVE-2024-57996) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1124-fips 5.4.0-1124.134 Available with Ubuntu Pro linux-image-5.4.0-1150-aws-fips 5.4.0-1150.160+fips1 Available with Ubuntu Pro linux-image-5.4.0-1153-gcp-fips 5.4.0-1153.162+fips1 Available with Ubuntu Pro linux-image-aws-fips 5.4.0.1150.97 Available with Ubuntu Pro linux-image-aws-fips-5.4 5.4.0.1150.97 Available with Ubuntu Pro linux-image-fips 5.4.0.1124.121 Available with Ubuntu Pro linux-image-fips-5.4 5.4.0.1124.121 Available with Ubuntu Pro linux-image-gcp-fips 5.4.0.1153.95 Available with UbuntuPro linux-image-gcp-fips-5.4 5.4.0.1153.95 Available with Ubuntu Pro After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
