========================================================================== Ubuntu Security Notice USN-8254-2 May 11, 2026 linux-nvidia, linux-nvidia-6.8, linux-nvidia-lowlatency vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-nvidia: Linux kernel for NVIDIA systems - linux-nvidia-lowlatency: Linux low latency kernel for NVIDIA systems - 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: - Network drivers; - NVME drivers; - Netfilter; (CVE-2026-23112, CVE-2026-23231, CVE-2026-23273) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1052-nvidia 6.8.0-1052.55 linux-image-6.8.0-1052-nvidia-64k 6.8.0-1052.55 linux-image-6.8.0-1052-nvidia-lowlatency 6.8.0-1052.55.1 linux-image-6.8.0-1052-nvidia-lowlatency-64k 6.8.0-1052.55.1 linux-image-nvidia 6.8.0-1052.55 linux-image-nvidia-6.8 6.8.0-1052.55 linux-image-nvidia-64k 6.8.0-1052.55 linux-image-nvidia-64k-6.8 6.8.0-1052.55 linux-image-nvidia-lowlatency 6.8.0-1052.55.1 linux-image-nvidia-lowlatency-6.8 6.8.0-1052.55.1 linux-image-nvidia-lowlatency-64k 6.8.0-1052.55.1 linux-image-nvidia-lowlatency-64k-6.8 6.8.0-1052.55.1 Ubuntu 22.04 LTS linux-image-6.8.0-1052-nvidia 6.8.0-1052.55~22.04.1 linux-image-6.8.0-1052-nvidia-64k 6.8.0-1052.55~22.04.1 linux-image-nvidia-6.8 6.8.0-1052.55~22.04.1 linux-image-nvidia-64k-6.8 6.8.0-1052.55~22.04.1 linux-image-nvidia-64k-hwe-22.04 6.8.0-1052.55~22.04.1 linux-image-nvidia-hwe-22.04 6.8.0-1052.55~22.04.1 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.
