This update corrects flaws in the following subsystems: - SMB network file system; (CVE-2025-22037, CVE-2025-37899) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1024-xilinx 6.8.0-1024.25 linux-image-6.8.0-1045-ibm 6.8.0-1045.45 linux-image-6.8.0-1047-aws 6.8.0-1047.50 linux-image-6.8.0-1047-aws-64k 6.8.0-1047.50 linux-image-aws-6.8 6.8.0-1047.50 linux-image-aws-64k-6.8 6.8.0-1047.50 linux-image-aws-64k-lts-24.04 6.8.0-1047.50 linux-image-aws-lts-24.04 6.8.0-1047.50 linux-image-ibm 6.8.0-1045.45 linux-image-ibm-6.8 6.8.0-1045.45 linux-image-ibm-classic 6.8.0-1045.45 linux-image-ibm-lts-24.04 6.8.0-1045.45 linux-image-xilinx 6.8.0.1024.25 linux-image-xilinx-6.8 6.8.0.1024.25 linux-image-xilinx-zynqmp 6.8.0.1024.25 Ubuntu 22.04 LTS linux-image-6.8.0-1045-ibm 6.8.0-1045.45~22.04.1 linux-image-6.8.0-1047-aws 6.8.0-1047.50~22.04.1 linux-image-6.8.0-1047-aws-64k 6.8.0-1047.50~22.04.1 linux-image-aws 6.8.0-1047.50~22.04.1 linux-image-aws-6.8 6.8.0-1047.50~22.04.1 linux-image-aws-64k 6.8.0-1047.50~22.04.1 linux-image-aws-64k-6.8 6.8.0-1047.50~22.04.1 linux-image-ibm-6.8 6.8.0-1045.45~22.04.1 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.
