--- title: 'USN-7766-1: Linux kernel vulnerabilities | Ubuntu security notices' description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/notices/USN-7766-1 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7766-1 --- # USN-7766-1: Linux kernel vulnerabilities Publication date 24 September 2025 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux-aws-6.8](https://ubuntu.com/security/cves?package=linux-aws-6.8) - Linux kernel for Amazon Web Services (AWS) systems * [linux-gcp-6.8](https://ubuntu.com/security/cves?package=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: * ARM32 architecture; * ARM64 architecture; * x86 architecture; * Compute Acceleration Framework; * Bus devices; * AMD CDX bus driver; * DPLL subsystem; * EFI core; * GPIO subsystem; * GPU drivers; * HID subsystem; * I2C subsystem; * InfiniBand drivers; * Multiple devices driver; * Network drivers; * Mellanox network drivers; * NVME drivers; * Pin controllers subsystem; * RapidIO drivers; * Voltage and Current Regulator drivers; * SCSI subsystem; * SLIMbus drivers; * QCOM SoC drivers; * UFS subsystem; * USB DSL drivers; * Renesas USBHS Controller drivers; * USB Type-C Connector System Software Interface... --- Show more ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) 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. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 22.04 LTS jammy | [linux-image-6.8.0-1039-aws](https://launchpad.net/ubuntu/+source/linux-signed-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-6.8.0-1039-aws-64k](https://launchpad.net/ubuntu/+source/linux-signed-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-6.8.0-1040-gcp](https://launchpad.net/ubuntu/+source/linux-signed-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-gcp-6.8/6.8.0-1040.42~22.04.1) | | | | [linux-image-6.8.0-1040-gcp-64k](https://launchpad.net/ubuntu/+source/linux-signed-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-gcp-6.8/6.8.0-1040.42~22.04.1) | | | | [linux-image-aws](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-aws-6.8](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-aws-64k](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-aws-64k-6.8](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8) –  [6.8.0-1039.41~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-aws-6.8/6.8.0-1039.41~22.04.1) | | | | [linux-image-gcp](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8/6.8.0-1040.42~22.04.1) | | | | [linux-image-gcp-6.8](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8/6.8.0-1040.42~22.04.1) | | | | [linux-image-gcp-64k](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8/6.8.0-1040.42~22.04.1) | | | | [linux-image-gcp-64k-6.8](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8) –  [6.8.0-1040.42~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-gcp-6.8/6.8.0-1040.42~22.04.1) | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
