========================================================================== Ubuntu Security Notice USN-8149-3 April 14, 2026 linux-azure, linux-azure-6.17 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 25.10 - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-6.17: Linux kernel for Microsoft Azure cloud 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 25.10 linux-image-6.17.0-1011-azure 6.17.0-1011.11 linux-image-azure 6.17.0-1011.11 linux-image-azure-6.17 6.17.0-1011.11 Ubuntu 24.04 LTS linux-image-6.17.0-1011-azure 6.17.0-1011.11~24.04.2 linux-image-azure 6.17.0-1011.11~24.04.2 linux-image-azure-6.17 6.17.0-1011.11~24.04.2 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.
