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-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems - linux-azure-5.4: Linux kernel for Microsoft Azure cloud systems - linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-5.4: Linux hardware enablement (HWE) kernel - linux-oracle-5.4: Linux kernel for Oracle 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: - Network drivers; - Ceph distributed file system; - Netfilter; (CVE-2023-52927, CVE-2023-52664, CVE-2024-26689) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1091-ibm 5.4.0-1091.96 linux-image-5.4.0-1132-kvm 5.4.0-1132.141 linux-image-5.4.0-1143-oracle 5.4.0-1143.153 linux-image-5.4.0-1145-aws 5.4.0-1145.155 linux-image-5.4.0-1148-gcp 5.4.0-1148.157 linux-image-5.4.0-215-generic 5.4.0-215.235 linux-image-5.4.0-215-generic-lpae 5.4.0-215.235 linux-image-5.4.0-215-lowlatency 5.4.0-215.235 linux-image-aws-lts-20.04 5.4.0.1145.142 linux-image-gcp-lts-20.04 5.4.0.1148.150 linux-image-generic 5.4.0.215.208 linux-image-generic-lpae 5.4.0.215.208 linux-image-ibm-lts-20.04 5.4.0.1091.120 linux-image-kvm 5.4.0.1132.128 linux-image-lowlatency 5.4.0.215.208 linux-image-oem 5.4.0.215.208 linux-image-oem-osp1 5.4.0.215.208 linux-image-oracle-lts-20.04 5.4.0.1143.137 linux-image-virtual 5.4.0.215.208 Ubuntu 18.04 LTS linux-image-5.4.0-1143-oracle 5.4.0-1143.153~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1145-aws 5.4.0-1145.155~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1148-gcp 5.4.0-1148.157~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1150-azure 5.4.0-1150.157~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-215-generic 5.4.0-215.235~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-215-lowlatency 5.4.0-215.235~18.04.1 Available with Ubuntu Pro linux-image-aws 5.4.0.1145.155~18.04.1 Available with Ubuntu Pro linux-image-azure 5.4.0.1150.157~18.04.1 Available with Ubuntu Pro linux-image-gcp 5.4.0.1148.157~18.04.1 Available with Ubuntu Pro linux-image-generic-hwe-18.04 5.4.0.215.235~18.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-18.04 5.4.0.215.235~18.04.1 Available with Ubuntu Pro linux-image-oem 5.4.0.215.235~18.04.1 Available with Ubuntu Pro linux-image-oem-osp1 5.4.0.215.235~18.04.1 Available with Ubuntu Pro linux-image-oracle 5.4.0.1143.153~18.04.1 Available with Ubuntu Pro linux-image-snapdragon-hwe-18.04 5.4.0.215.235~18.04.1 Available with Ubuntu Pro linux-image-virtual-hwe-18.04 5.4.0.215.235~18.04.1 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.
