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-gke: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-nvidia: Linux kernel for NVIDIA systems - linux-nvidia-lowlatency: Linux low latency kernel for NVIDIA systems - linux-oem-6.8: Linux kernel for OEM systems - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-gcp-6.8: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-6.8: Linux hardware enablement (HWE) 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: - File systems infrastructure; - Network traffic control; (CVE-2024-46800, CVE-2024-43882) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1014-gke 6.8.0-1014.18 linux-image-6.8.0-1015-raspi 6.8.0-1015.17 linux-image-6.8.0-1016-ibm 6.8.0-1016.16 linux-image-6.8.0-1016-oracle 6.8.0-1016.17 linux-image-6.8.0-1016-oracle-64k 6.8.0-1016.17 linux-image-6.8.0-1017-oem 6.8.0-1017.17 linux-image-6.8.0-1018-gcp 6.8.0-1018.20 linux-image-6.8.0-1018-nvidia 6.8.0-1018.20 linux-image-6.8.0-1018-nvidia-64k 6.8.0-1018.20 linux-image-6.8.0-1018-nvidia-lowlatency 6.8.0-1018.20.1 linux-image-6.8.0-1018-nvidia-lowlatency-64k 6.8.0-1018.20.1 linux-image-6.8.0-1019-aws 6.8.0-1019.21 linux-image-6.8.0-49-generic 6.8.0-49.49 linux-image-6.8.0-49-generic-64k 6.8.0-49.49 linux-image-aws 6.8.0-1019.21 linux-image-gcp 6.8.0-1018.20 linux-image-generic 6.8.0-49.49 linux-image-generic-64k 6.8.0-49.49 linux-image-generic-64k-hwe-24.04 6.8.0-49.49 linux-image-generic-hwe-24.04 6.8.0-49.49 linux-image-generic-lpae 6.8.0-49.49 linux-image-gke 6.8.0-1014.18 linux-image-ibm 6.8.0-1016.16 linux-image-ibm-classic 6.8.0-1016.16 linux-image-ibm-lts-24.04 6.8.0-1016.16 linux-image-kvm 6.8.0-49.49 linux-image-nvidia 6.8.0-1018.20 linux-image-nvidia-64k 6.8.0-1018.20 linux-image-nvidia-lowlatency 6.8.0-1018.20.1 linux-image-nvidia-lowlatency-64k 6.8.0-1018.20.1 linux-image-oem-24.04 6.8.0-1017.17 linux-image-oem-24.04a 6.8.0-1017.17 linux-image-oracle 6.8.0-1016.17 linux-image-oracle-64k 6.8.0-1016.17 linux-image-raspi 6.8.0-1015.17 linux-image-virtual 6.8.0-49.49 linux-image-virtual-hwe-24.04 6.8.0-49.49 Ubuntu 22.04 LTS linux-image-6.8.0-1018-gcp 6.8.0-1018.20~22.04.1 linux-image-6.8.0-1018-nvidia 6.8.0-1018.20~22.04.1 linux-image-6.8.0-1018-nvidia-64k 6.8.0-1018.20~22.04.1 linux-image-6.8.0-49-generic 6.8.0-49.49~22.04.1 linux-image-6.8.0-49-generic-64k 6.8.0-49.49~22.04.1 linux-image-gcp 6.8.0-1018.20~22.04.1 linux-image-generic-64k-hwe-22.04 6.8.0-49.49~22.04.1 linux-image-generic-hwe-22.04 6.8.0-49.49~22.04.1 linux-image-nvidia-6.8 6.8.0-1018.20~22.04.1 linux-image-nvidia-64k-6.8 6.8.0-1018.20~22.04.1 linux-image-nvidia-64k-hwe-22.04 6.8.0-1018.20~22.04.1 linux-image-nvidia-hwe-22.04 6.8.0-1018.20~22.04.1 linux-image-oem-22.04 6.8.0-49.49~22.04.1 linux-image-oem-22.04a 6.8.0-49.49~22.04.1 linux-image-oem-22.04b 6.8.0-49.49~22.04.1 linux-image-oem-22.04c 6.8.0-49.49~22.04.1 linux-image-oem-22.04d 6.8.0-49.49~22.04.1 linux-image-virtual-hwe-22.04 6.8.0-49.49~22.04.1 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.
