Software Description: - linux-aws-6.8: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp-6.8: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-6.8: Linux hardware enablement (HWE) kernel - linux-ibm-6.8: Linux kernel for IBM cloud 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: - Cryptographic API; - Netfilter; - Network traffic control; (CVE-2026-23060, CVE-2026-23074, CVE-2026-23111) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-6.8.0-1050-ibm 6.8.0-1050.50~22.04.1 linux-image-6.8.0-1050-nvidia 6.8.0-1050.53~22.04.1 linux-image-6.8.0-1050-nvidia-64k 6.8.0-1050.53~22.04.1 linux-image-6.8.0-1051-aws 6.8.0-1051.54~22.04.1 linux-image-6.8.0-1051-aws-64k 6.8.0-1051.54~22.04.1 linux-image-6.8.0-1053-gcp 6.8.0-1053.56~22.04.1 linux-image-6.8.0-1053-gcp-64k 6.8.0-1053.56~22.04.1 linux-image-6.8.0-107-generic 6.8.0-107.107~22.04.1 linux-image-6.8.0-107-generic-64k 6.8.0-107.107~22.04.1 linux-image-6.8.0-107-lowlatency 6.8.0-107.107.1~22.04.1 linux-image-6.8.0-107-lowlatency-64k 6.8.0-107.107.1~22.04.1 linux-image-aws 6.8.0-1051.54~22.04.1 linux-image-aws-6.8 6.8.0-1051.54~22.04.1 linux-image-aws-64k 6.8.0-1051.54~22.04.1 linux-image-aws-64k-6.8 6.8.0-1051.54~22.04.1 linux-image-gcp 6.8.0-1053.56~22.04.1 linux-image-gcp-6.8 6.8.0-1053.56~22.04.1 linux-image-gcp-64k 6.8.0-1053.56~22.04.1 linux-image-gcp-64k-6.8 6.8.0-1053.56~22.04.1 linux-image-generic-6.8 6.8.0-107.107~22.04.1 linux-image-generic-64k-6.8 6.8.0-107.107~22.04.1 linux-image-generic-64k-hwe-22.04 6.8.0-107.107~22.04.1 linux-image-generic-hwe-22.04 6.8.0-107.107~22.04.1 linux-image-ibm-6.8 6.8.0-1050.50~22.04.1 linux-image-lowlatency-6.8 6.8.0-107.107.1~22.04.1 linux-image-lowlatency-64k-6.8 6.8.0-107.107.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.8.0-107.107.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.8.0-107.107.1~22.04.1 linux-image-nvidia-6.8 6.8.0-1050.53~22.04.1 linux-image-nvidia-64k-6.8 6.8.0-1050.53~22.04.1 linux-image-nvidia-64k-hwe-22.04 6.8.0-1050.53~22.04.1 linux-image-nvidia-hwe-22.04 6.8.0-1050.53~22.04.1 linux-image-oem-22.04 6.8.0-107.107~22.04.1 linux-image-oem-22.04a 6.8.0-107.107~22.04.1 linux-image-oem-22.04b 6.8.0-107.107~22.04.1 linux-image-oem-22.04c 6.8.0-107.107~22.04.1 linux-image-oem-22.04d 6.8.0-107.107~22.04.1 linux-image-virtual-6.8 6.8.0-107.107~22.04.1 linux-image-virtual-hwe-22.04 6.8.0-107.107~22.04.1 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.
