========================================================================== Ubuntu Security Notice USN-8112-2 March 20, 2026 linux-aws-fips, linux-fips, linux-gcp-fips vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 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: - x86 architecture; - MMC subsystem; - Network drivers; - USB Device Class drivers; - BTRFS file system; - HFS+ file system; - XFRM subsystem; - IPv4 networking; - IPv6 networking; - MAC80211 subsystem; - Simplified Mandatory Access Control Kernel framework; (CVE-2021-47599, CVE-2022-48875, CVE-2022-49267, CVE-2024-47659, CVE-2024-49927, CVE-2024-56548, CVE-2024-56581, CVE-2024-56593, CVE-2025-21704, CVE-2025-40215) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS linux-image-4.15.0-1144-fips 4.15.0-1144.156 Available with Ubuntu Pro linux-image-4.15.0-2090-gcp-fips 4.15.0-2090.96 Available with Ubuntu Pro linux-image-4.15.0-2127-aws-fips 4.15.0-2127.133 Available with Ubuntu Pro linux-image-aws-fips 4.15.0.2127.121 Available with Ubuntu Pro linux-image-aws-fips-4.15 4.15.0.2127.121 Available with Ubuntu Pro linux-image-fips 4.15.0.1144.141 Available with Ubuntu Pro linux-image-gcp-fips 4.15.0.2090.88 Available with Ubuntu Pro linux-image-gcp-fips-4.15 4.15.0.2090.88 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.
