Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-iot: Linux kernel for IoT platforms - linux-kvm: Linux kernel for cloud environments - linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-5.4: Linux hardware enablement (HWE) kernel - linux-ibm-5.4: Linux kernel for IBM cloud systems 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; - Padata parallel execution mechanism; - Netfilter; (CVE-2022-49698, CVE-2025-21726, CVE-2025-40019) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1058-iot 5.4.0-1058.61 Available with Ubuntu Pro linux-image-5.4.0-1100-ibm 5.4.0-1100.105 Available with Ubuntu Pro linux-image-5.4.0-1141-kvm 5.4.0-1141.150 Available with Ubuntu Pro linux-image-5.4.0-1154-aws 5.4.0-1154.164 Available with Ubuntu Pro linux-image-5.4.0-1157-gcp 5.4.0-1157.166 Available with Ubuntu Pro linux-image-5.4.0-225-generic 5.4.0-225.245 Available with Ubuntu Pro linux-image-5.4.0-225-generic-lpae 5.4.0-225.245 Available with Ubuntu Pro linux-image-5.4.0-225-lowlatency 5.4.0-225.245 Available with Ubuntu Pro linux-image-aws-5.4 5.4.0.1154.151 Available with Ubuntu Pro linux-image-aws-lts-20.04 5.4.0.1154.151 Available with Ubuntu Pro linux-image-gcp-5.4 5.4.0.1157.159 Available with Ubuntu Pro linux-image-gcp-lts-20.04 5.4.0.1157.159 Available with Ubuntu Pro linux-image-generic 5.4.0.225.217 Available with Ubuntu Pro linux-image-generic-5.4 5.4.0.225.217 Available with Ubuntu Pro linux-image-generic-lpae 5.4.0.225.217 Available with Ubuntu Pro linux-image-generic-lpae-5.4 5.4.0.225.217 Available with Ubuntu Pro linux-image-ibm-5.4 5.4.0.1100.129 Available with Ubuntu Pro linux-image-ibm-lts-20.04 5.4.0.1100.129 Available with Ubuntu Pro linux-image-kvm 5.4.0.1141.137 Available with Ubuntu Pro linux-image-kvm-5.4 5.4.0.1141.137 Available with Ubuntu Pro linux-image-lowlatency 5.4.0.225.217 Available with Ubuntu Pro linux-image-lowlatency-5.4 5.4.0.225.217 Available with Ubuntu Pro linux-image-oem 5.4.0.225.217 Available with Ubuntu Pro linux-image-oem-osp1 5.4.0.225.217 Available with Ubuntu Pro linux-image-virtual 5.4.0.225.217 Available with Ubuntu Pro linux-image-virtual-5.4 5.4.0.225.217 Available with Ubuntu Pro Ubuntu 18.04 LTS linux-image-5.4.0-1100-ibm 5.4.0-1100.105~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1154-aws 5.4.0-1154.164~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1157-gcp 5.4.0-1157.166~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-225-generic 5.4.0-225.245~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-225-lowlatency 5.4.0-225.245~18.04.1 Available with Ubuntu Pro linux-image-aws 5.4.0.1154.164~18.04.1 Available with Ubuntu Pro linux-image-aws-5.4 5.4.0.1154.164~18.04.1 Available with Ubuntu Pro linux-image-gcp 5.4.0.1157.166~18.04.1 Available with Ubuntu Pro linux-image-gcp-5.4 5.4.0.1157.166~18.04.1 Available with Ubuntu Pro linux-image-generic-5.4 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-generic-hwe-18.04 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-ibm 5.4.0.1100.105~18.04.1 Available with Ubuntu Pro linux-image-ibm-5.4 5.4.0.1100.105~18.04.1 Available with Ubuntu Pro linux-image-ibm-edge 5.4.0.1100.105~18.04.1 Available with Ubuntu Pro linux-image-lowlatency-5.4 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-18.04 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-oem 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-oem-osp1 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-snapdragon-5.4 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-snapdragon-hwe-18.04 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-virtual-5.4 5.4.0.225.245~18.04.1 Available with Ubuntu Pro linux-image-virtual-hwe-18.04 5.4.0.225.245~18.04.1 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.
