security advisorycriticalUbuntuUbuntu 24.04 LTS Kernel Critical Flaws April 2026 USN-8148-2
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-8148-2 April 02, 2026 linux-fips, linux-aws-fips, linux-gcp-fips vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. 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: - Cryptographic API; - Netfilter; - Network traffic control; (CVE-2026-23060, CVE-2026-23074, CVE-2026-23111) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1051-aws-fips 6.8.0-1051.54+fips1 Available with Ubuntu Pro linux-image-6.8.0-1053-gcp-fips 6.8.0-1053.56+fips1 Available with Ubuntu Pro linux-image-6.8.0-107-fips 6.8.0-107.107+fips1 Available with Ubuntu Pro linux-image-aws-fips 6.8.0-1051.54+fips1 Available with Ubuntu Pro linux-image-aws-fips-6.8 6.8.0-1051.54+fips1 Available with Ubuntu Pro linux-image-fips 6.8.0-107.107+fips1 Available with Ubuntu Pro linux-image-fips-6.8 6.8.0-107.107+fips1 Available with Ubuntu Pro linux-image-gcp-fips 6.8.0-1053.56+fips1 Available with Ubuntu Pro linux-image-gcp-fips-6.8 6.8.0-1053.56+fips1 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.
