Software Description: - linux-aws-fips: Linux kernel for Amazon Web Services (AWS) systems with FIPS - linux-fips: Linux kernel with FIPS - linux-gcp-fips: Linux kernel for Google Cloud Platform (GCP) systems with FIPS Details: Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Packet sockets; - Network traffic control; - VMware vSockets driver; (CVE-2025-38618, CVE-2025-38617, CVE-2025-38477) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1093-aws-fips 5.15.0-1093.100+fips1 Available with Ubuntu Pro linux-image-5.15.0-1093-gcp-fips 5.15.0-1093.102+fips1 Available with Ubuntu Pro linux-image-5.15.0-157-fips 5.15.0-157.167+fips1 Available with Ubuntu Pro linux-image-aws-fips 5.15.0.1093.89 Available with Ubuntu Pro linux-image-aws-fips-5.15 5.15.0.1093.89 Available with Ubuntu Pro linux-image-fips 5.15.0.157.90 Available with Ubuntu Pro linux-image-fips-5.15 5.15.0.157.90 Available with Ubuntu Pro linux-image-gcp-fips 5.15.0.1093.83 Available with Ubuntu Pro linux-image-gcp-fips-5.15 5.15.0.1093.83 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.
