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-realtime: Linux kernel for Real-time systems - linux-aws-6.17: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp-6.17: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-6.17: Linux hardware enablement (HWE) kernel 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 25.10 linux-image-6.17.0-1009-realtime 6.17.0-1009.10 linux-image-6.17.0-1010-aws 6.17.0-1010.10 linux-image-6.17.0-1010-aws-64k 6.17.0-1010.10 linux-image-6.17.0-1010-gcp 6.17.0-1010.10 linux-image-6.17.0-1010-gcp-64k 6.17.0-1010.10 linux-image-6.17.0-20-generic 6.17.0-20.20 linux-image-6.17.0-20-generic-64k 6.17.0-20.20 linux-image-aws 6.17.0-1010.10 linux-image-aws-6.17 6.17.0-1010.10 linux-image-aws-64k 6.17.0-1010.10 linux-image-aws-64k-6.17 6.17.0-1010.10 linux-image-gcp 6.17.0-1010.10 linux-image-gcp-6.17 6.17.0-1010.10 linux-image-gcp-64k 6.17.0-1010.10 linux-image-gcp-64k-6.17 6.17.0-1010.10 linux-image-generic 6.17.0-20.20 linux-image-generic-6.17 6.17.0-20.20 linux-image-generic-64k 6.17.0-20.20 linux-image-generic-64k-6.17 6.17.0-20.20 linux-image-realtime 6.17.0-1009.10 linux-image-realtime-6.17 6.17.0-1009.10 linux-image-virtual 6.17.0-20.20 linux-image-virtual-6.17 6.17.0-20.20 Ubuntu 24.04 LTS linux-image-6.17.0-1010-aws 6.17.0-1010.10~24.04.1 linux-image-6.17.0-1010-aws-64k 6.17.0-1010.10~24.04.1 linux-image-6.17.0-1010-gcp 6.17.0-1010.10~24.04.1 linux-image-6.17.0-1010-gcp-64k 6.17.0-1010.10~24.04.1 linux-image-6.17.0-20-generic 6.17.0-20.20~24.04.1 linux-image-6.17.0-20-generic-64k 6.17.0-20.20~24.04.1 linux-image-aws 6.17.0-1010.10~24.04.1 linux-image-aws-6.17 6.17.0-1010.10~24.04.1 linux-image-aws-64k 6.17.0-1010.10~24.04.1 linux-image-aws-64k-6.17 6.17.0-1010.10~24.04.1 linux-image-gcp 6.17.0-1010.10~24.04.1 linux-image-gcp-6.17 6.17.0-1010.10~24.04.1 linux-image-gcp-64k 6.17.0-1010.10~24.04.1 linux-image-gcp-64k-6.17 6.17.0-1010.10~24.04.1 linux-image-generic-6.17 6.17.0-20.20~24.04.1 linux-image-generic-64k-6.17 6.17.0-20.20~24.04.1 linux-image-generic-64k-hwe-24.04 6.17.0-20.20~24.04.1 linux-image-generic-hwe-24.04 6.17.0-20.20~24.04.1 linux-image-virtual-6.17 6.17.0-20.20~24.04.1 linux-image-virtual-hwe-24.04 6.17.0-20.20~24.04.1 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.
