--- title: 'USN-7703-3: Linux kernel (Oracle) 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-7703-3 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7703-3 --- # USN-7703-3: Linux kernel (Oracle) vulnerabilities Publication date 21 August 2025 Overview Several security issues were fixed in the Linux kernel. Releases [24.04 LTS](https://ubuntu.com/security/notices?release=noble) [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux-oracle](https://ubuntu.com/security/cves?package=linux-oracle) - Linux kernel for Oracle Cloud systems * [linux-oracle-6.8](https://ubuntu.com/security/cves?package=linux-oracle-6.8) - Linux kernel for Oracle Cloud 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: * ARM64 architecture; * PowerPC architecture; * x86 architecture; * Block layer subsystem; * GPIO subsystem; * GPU drivers; * HID subsystem; * Input Device (Mouse) drivers; * Multiple devices driver; * Media drivers; * Network drivers; * PCI subsystem; * S/390 drivers; * SPI subsystem; * Trusted Execution Environment drivers; * UFS subsystem; * USB Device Class drivers; * USB core drivers; * USB Gadget drivers; * Framebuffer layer; * Network file system (NFS) client; * Network file system (NFS) server daemon; * File systems infrastructure; * SMB network file system; * Networking core; * L3 Master device support... --- 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 | | --- | --- | | 24.04 LTS noble | [linux-image-6.8.0-1032-oracle](https://launchpad.net/ubuntu/+source/linux-signed-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-signed-oracle/6.8.0-1032.33) | | | | [linux-image-6.8.0-1032-oracle-64k](https://launchpad.net/ubuntu/+source/linux-signed-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-signed-oracle/6.8.0-1032.33) | | | | [linux-image-oracle-6.8](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.8.0-1032.33) | | | | [linux-image-oracle-64k-6.8](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.8.0-1032.33) | | | | [linux-image-oracle-64k-lts-24.04](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.8.0-1032.33) | | | | [linux-image-oracle-lts-24.04](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.8.0-1032.33](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.8.0-1032.33) | | | | 22.04 LTS jammy | [linux-image-6.8.0-1032-oracle](https://launchpad.net/ubuntu/+source/linux-signed-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-oracle-6.8/6.8.0-1032.33~22.04.1) | | | | [linux-image-6.8.0-1032-oracle-64k](https://launchpad.net/ubuntu/+source/linux-signed-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-signed-oracle-6.8/6.8.0-1032.33~22.04.1) | | | | [linux-image-oracle](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8/6.8.0-1032.33~22.04.1) | | | | [linux-image-oracle-6.8](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8/6.8.0-1032.33~22.04.1) | | | | [linux-image-oracle-64k](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8/6.8.0-1032.33~22.04.1) | | | | [linux-image-oracle-64k-6.8](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8) –  [6.8.0-1032.33~22.04.1](https://launchpad.net/ubuntu/+source/linux-meta-oracle-6.8/6.8.0-1032.33~22.04.1) | | | --- ### 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.
