Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-lowlatency: Linux low latency kernel - linux-nvidia: Linux kernel for NVIDIA systems - linux-nvidia-lowlatency: Linux low latency kernel for NVIDIA systems - linux-oracle: Linux kernel for Oracle Cloud systems - linux-aws-6.8: Linux kernel for Amazon Web Services (AWS) systems - linux-lowlatency-hwe-6.8: Linux low latency kernel - linux-nvidia-6.8: Linux kernel for NVIDIA 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: - Media drivers; - Network drivers; - Netfilter; - TLS protocol; (CVE-2025-21729, CVE-2025-38227, CVE-2025-38616, CVE-2025-38678) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1040-oracle 6.8.0-1040.41 linux-image-6.8.0-1040-oracle-64k 6.8.0-1040.41 linux-image-6.8.0-1041-ibm 6.8.0-1041.41 linux-image-6.8.0-1043-aws 6.8.0-1043.45 linux-image-6.8.0-1043-aws-64k 6.8.0-1043.45 linux-image-6.8.0-1043-nvidia 6.8.0-1043.46 linux-image-6.8.0-1043-nvidia-64k 6.8.0-1043.46 linux-image-6.8.0-1043-nvidia-lowlatency 6.8.0-1043.46.1 linux-image-6.8.0-1043-nvidia-lowlatency-64k 6.8.0-1043.46.1 linux-image-6.8.0-88-generic 6.8.0-88.89 linux-image-6.8.0-88-generic-64k 6.8.0-88.89 linux-image-6.8.0-88-lowlatency 6.8.0-88.89.1 linux-image-6.8.0-88-lowlatency-64k 6.8.0-88.89.1 linux-image-aws-6.8 6.8.0-1043.45 linux-image-aws-64k-6.8 6.8.0-1043.45 linux-image-aws-64k-lts-24.04 6.8.0-1043.45 linux-image-aws-lts-24.04 6.8.0-1043.45 linux-image-generic 6.8.0-88.89 linux-image-generic-6.8 6.8.0-88.89 linux-image-generic-64k 6.8.0-88.89 linux-image-generic-64k-6.8 6.8.0-88.89 linux-image-generic-lpae 6.8.0-88.89 linux-image-ibm 6.8.0-1041.41 linux-image-ibm-6.8 6.8.0-1041.41 linux-image-ibm-classic 6.8.0-1041.41 linux-image-ibm-lts-24.04 6.8.0-1041.41 linux-image-kvm 6.8.0-88.89 linux-image-lowlatency 6.8.0-88.89.1 linux-image-lowlatency-6.8 6.8.0-88.89.1 linux-image-lowlatency-64k 6.8.0-88.89.1 linux-image-lowlatency-64k-6.8 6.8.0-88.89.1 linux-image-nvidia 6.8.0-1043.46 linux-image-nvidia-6.8 6.8.0-1043.46 linux-image-nvidia-64k 6.8.0-1043.46 linux-image-nvidia-64k-6.8 6.8.0-1043.46 linux-image-nvidia-lowlatency 6.8.0-1043.46.1 linux-image-nvidia-lowlatency-6.8 6.8.0-1043.46.1 linux-image-nvidia-lowlatency-64k 6.8.0-1043.46.1 linux-image-nvidia-lowlatency-64k-6.8 6.8.0-1043.46.1 linux-image-oracle-6.8 6.8.0-1040.41 linux-image-oracle-64k-6.8 6.8.0-1040.41 linux-image-oracle-64k-lts-24.04 6.8.0-1040.41 linux-image-oracle-lts-24.04 6.8.0-1040.41 linux-image-virtual 6.8.0-88.89 linux-image-virtual-6.8 6.8.0-88.89 Ubuntu 22.04 LTS linux-image-6.8.0-1043-aws 6.8.0-1043.45~22.04.1 linux-image-6.8.0-1043-aws-64k 6.8.0-1043.45~22.04.1 linux-image-6.8.0-1043-nvidia 6.8.0-1043.46~22.04.1 linux-image-6.8.0-1043-nvidia-64k 6.8.0-1043.46~22.04.1 linux-image-6.8.0-88-lowlatency 6.8.0-88.89.1~22.04.1 linux-image-6.8.0-88-lowlatency-64k 6.8.0-88.89.1~22.04.1 linux-image-aws 6.8.0-1043.45~22.04.1 linux-image-aws-6.8 6.8.0-1043.45~22.04.1 linux-image-aws-64k 6.8.0-1043.45~22.04.1 linux-image-aws-64k-6.8 6.8.0-1043.45~22.04.1 linux-image-lowlatency-6.8 6.8.0-88.89.1~22.04.1 linux-image-lowlatency-64k-6.8 6.8.0-88.89.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.8.0-88.89.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.8.0-88.89.1~22.04.1 linux-image-nvidia-6.8 6.8.0-1043.46~22.04.1 linux-image-nvidia-64k-6.8 6.8.0-1043.46~22.04.1 linux-image-nvidia-64k-hwe-22.04 6.8.0-1043.46~22.04.1 linux-image-nvidia-hwe-22.04 6.8.0-1043.46~22.04.1 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.
