========================================================================== Ubuntu Security Notice USN-6872-2 July 04, 2024
linux-lowlatency, linux-lowlatency-hwe-6.5 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-lowlatency: Linux low latency kernel - linux-lowlatency-hwe-6.5: Linux low latency 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 subsystem: - Netfilter; (CVE-2024-26809, CVE-2024-26643, CVE-2024-26925, CVE-2024-26924) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10 linux-image-6.5.0-42-lowlatency 6.5.0-42.42.1 linux-image-6.5.0-42-lowlatency-64k 6.5.0-42.42.1 linux-image-lowlatency 6.5.0.42.42.1 linux-image-lowlatency-64k 6.5.0.42.42.1 Ubuntu 22.04 LTS linux-image-6.5.0-42-lowlatency 6.5.0-42.42.1~22.04.1 linux-image-6.5.0-42-lowlatency-64k 6.5.0-42.42.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.5.0.42.42.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.5.0.42.42.1~22.04.1 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.
