========================================================================== Ubuntu Security Notice USN-7682-5 August 12, 2025 linux-gcp-6.8, linux-raspi vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-raspi: Linux kernel for Raspberry Pi systems - linux-gcp-6.8: Linux kernel for Google Cloud Platform (GCP) 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: - Network traffic control; (CVE-2025-38083, CVE-2025-37797) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1032-raspi 6.8.0-1032.36 linux-image-raspi 6.8.0-1032.36 linux-image-raspi-6.8 6.8.0-1032.36 Ubuntu 22.04 LTS linux-image-6.8.0-1034-gcp 6.8.0-1034.36~22.04.2 linux-image-6.8.0-1034-gcp-64k 6.8.0-1034.36~22.04.2 linux-image-gcp 6.8.0-1034.36~22.04.2 linux-image-gcp-6.8 6.8.0-1034.36~22.04.2 linux-image-gcp-64k 6.8.0-1034.36~22.04.2 linux-image-gcp-64k-6.8 6.8.0-1034.36~22.04.2 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.
