Software Description: - linux: Linux kernel - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-bluefield: Linux kernel for NVIDIA BlueField platforms - 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-azure-5.4: Linux kernel for Microsoft Azure cloud 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: - GPU drivers; - Network drivers; - File systems infrastructure; - Ext4 file system; - Network file system (NFS) server daemon; - Bluetooth subsystem; - IPv6 networking; - Network traffic control; (CVE-2024-53237, CVE-2024-50256, CVE-2021-47119, CVE-2024-35958, CVE-2025-21700, CVE-2025-21703, CVE-2024-56651, CVE-2024-49974, CVE-2025-21702, CVE-2024-26915, CVE-2024-46826) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1090-ibm 5.4.0-1090.95 linux-image-5.4.0-1103-bluefield 5.4.0-1103.110 linux-image-5.4.0-1131-kvm 5.4.0-1131.140 linux-image-5.4.0-1142-oracle 5.4.0-1142.152 linux-image-5.4.0-1147-gcp 5.4.0-1147.156 linux-image-5.4.0-1149-azure 5.4.0-1149.156 linux-image-5.4.0-214-generic 5.4.0-214.234 linux-image-5.4.0-214-generic-lpae 5.4.0-214.234 linux-image-5.4.0-214-lowlatency 5.4.0-214.234 linux-image-azure-lts-20.04 5.4.0.1149.143 linux-image-bluefield 5.4.0.1103.99 linux-image-gcp-lts-20.04 5.4.0.1147.149 linux-image-generic 5.4.0.214.207 linux-image-generic-lpae 5.4.0.214.207 linux-image-ibm-lts-20.04 5.4.0.1090.119 linux-image-kvm 5.4.0.1131.127 linux-image-lowlatency 5.4.0.214.207 linux-image-oem 5.4.0.214.207 linux-image-oem-osp1 5.4.0.214.207 linux-image-oracle-lts-20.04 5.4.0.1142.136 linux-image-virtual 5.4.0.214.207 Ubuntu 18.04 LTS linux-image-5.4.0-1142-oracle 5.4.0-1142.152~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-1149-azure 5.4.0-1149.156~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-214-generic 5.4.0-214.234~18.04.1 Available with Ubuntu Pro linux-image-5.4.0-214-lowlatency 5.4.0-214.234~18.04.1 Available with Ubuntu Pro linux-image-azure 5.4.0.1149.156~18.04.1 Available with Ubuntu Pro linux-image-generic-hwe-18.04 5.4.0.214.234~18.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-18.04 5.4.0.214.234~18.04.1 Available with Ubuntu Pro linux-image-oem 5.4.0.214.234~18.04.1 Available with Ubuntu Pro linux-image-oem-osp1 5.4.0.214.234~18.04.1 Available with Ubuntu Pro linux-image-oracle 5.4.0.1142.152~18.04.1 Available with Ubuntu Pro linux-image-snapdragon-hwe-18.04 5.4.0.214.234~18.04.1 Available with Ubuntu Pro linux-image-virtual-hwe-18.04 5.4.0.214.234~18.04.1 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.
