Software Description: - linux-azure-nvidia: Linux kernel for Microsoft Azure Cloud systems, N-Series - linux-azure-6.8: Linux kernel for Microsoft Azure cloud systems Details: Several security issues were discovered in the Linux kernel.

This update corrects flaws in the following subsystems: - InfiniBand drivers; - Netfilter; - Network traffic control; (CVE-2025-38001, CVE-2025-37798, CVE-2025-37932, CVE-2025-37997, CVE-2025-38000, CVE-2025-22088, CVE-2025-37890) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1019-azure-nvidia 6.8.0-1019.20 linux-image-azure-nvidia 6.8.0-1019.20 linux-image-azure-nvidia-6.8 6.8.0-1019.20 Ubuntu 22.04 LTS linux-image-6.8.0-1031-azure 6.8.0-1031.36~22.04.1 linux-image-6.8.0-1031-azure-fde 6.8.0-1031.36~22.04.1 linux-image-azure 6.8.0-1031.36~22.04.1 linux-image-azure-6.8 6.8.0-1031.36~22.04.1 linux-image-azure-fde 6.8.0-1031.36~22.04.1 linux-image-azure-fde-6.8 6.8.0-1031.36~22.04.1 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.
