Software Description: - linux: Linux kernel - linux-gkeop: Linux kernel for Google Container Engine (GKE) systems - linux-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-hwe-6.8: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-6.8: 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 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-6.8.0-101-generic 6.8.0-101.101 linux-image-6.8.0-101-generic-64k 6.8.0-101.101 linux-image-6.8.0-101-lowlatency 6.8.0-101.101.1 linux-image-6.8.0-101-lowlatency-64k 6.8.0-101.101.1 linux-image-6.8.0-1031-gkeop 6.8.0-1031.34 linux-image-6.8.0-1044-oracle 6.8.0-1044.45 linux-image-6.8.0-1044-oracle-64k 6.8.0-1044.45 linux-image-6.8.0-1048-raspi 6.8.0-1048.52 linux-image-generic 6.8.0-101.101 linux-image-generic-6.8 6.8.0-101.101 linux-image-generic-64k 6.8.0-101.101 linux-image-generic-64k-6.8 6.8.0-101.101 linux-image-generic-lpae 6.8.0-101.101 linux-image-gkeop 6.8.0-1031.34 linux-image-gkeop-6.8 6.8.0-1031.34 linux-image-intel-iotg 6.8.0-101.101 linux-image-kvm 6.8.0-101.101 linux-image-lowlatency 6.8.0-101.101.1 linux-image-lowlatency-6.8 6.8.0-101.101.1 linux-image-lowlatency-64k 6.8.0-101.101.1 linux-image-lowlatency-64k-6.8 6.8.0-101.101.1 linux-image-oracle-6.8 6.8.0-1044.45 linux-image-oracle-64k-6.8 6.8.0-1044.45 linux-image-oracle-64k-lts-24.04 6.8.0-1044.45 linux-image-oracle-lts-24.04 6.8.0-1044.45 linux-image-raspi 6.8.0-1048.52 linux-image-raspi-6.8 6.8.0-1048.52 linux-image-virtual 6.8.0-101.101 linux-image-virtual-6.8 6.8.0-101.101 Ubuntu 22.04 LTS linux-image-6.8.0-101-generic 6.8.0-101.101~22.04.1 linux-image-6.8.0-101-generic-64k 6.8.0-101.101~22.04.1 linux-image-6.8.0-101-lowlatency 6.8.0-101.101.1~22.04.1 linux-image-6.8.0-101-lowlatency-64k 6.8.0-101.101.1~22.04.1 linux-image-generic-6.8 6.8.0-101.101~22.04.1 linux-image-generic-64k-6.8 6.8.0-101.101~22.04.1 linux-image-generic-64k-hwe-22.04 6.8.0-101.101~22.04.1 linux-image-generic-hwe-22.04 6.8.0-101.101~22.04.1 linux-image-lowlatency-6.8 6.8.0-101.101.1~22.04.1 linux-image-lowlatency-64k-6.8 6.8.0-101.101.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.8.0-101.101.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.8.0-101.101.1~22.04.1 linux-image-oem-22.04 6.8.0-101.101~22.04.1 linux-image-oem-22.04a 6.8.0-101.101~22.04.1 linux-image-oem-22.04b 6.8.0-101.101~22.04.1 linux-image-oem-22.04c 6.8.0-101.101~22.04.1 linux-image-oem-22.04d 6.8.0-101.101~22.04.1 linux-image-virtual-6.8 6.8.0-101.101~22.04.1 linux-image-virtual-hwe-22.04 6.8.0-101.101~22.04.1 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.
