5.15.0.203.213~20.04.1 Available with Ubuntu Pro 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.

Multiple Ubuntu Linux Kernel Vulnerabilities Addressed in Recent Updates On November 10, 2026, Ubuntu released kernel updates addressing several security vulnerabilities across various versions, including 18.04, 20.04, and 22.04 LTS. These updates fix issues related to networking and filesystems, as well as specific flaws in the x86 architecture and OCFS2 filesystem. Notably, CVE-2026-63940 and CVE-2026-74350, both rated critical with CVSS scores of 9.3 and 9.8 respectively, were among the vulnerabilities patched. The updates affect multiple cloud environments, including AWS, Azure, and GCP systems. Users are advised to update their systems promptly to mitigate potential exploitation risks. The updates require a reboot to apply changes, and users must recompile any third-party kernel modules due to ABI changes. The vulnerabilities could allow attackers to compromise affected systems if left. 3 sources 61
