[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7156-1 --- # USN-7156-1: Linux kernel (GKE) vulnerabilities Publication date 12 December 2024 Overview Several security issues were fixed in the Linux kernel. Releases [24.04 LTS](https://ubuntu.com/security/notices?release=noble) --- Open side navigation ## Packages * [linux-gkeop](https://ubuntu.com/security/cves?package=linux-gkeop) - Linux kernel for Google Container Engine (GKE) systems ## Details Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. ([CVE-2024-25741](https://ubuntu.com/security/CVE-2024-25741)) 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; * MIPS architecture; * PA-RISC architecture; * PowerPC architecture; * RISC-V architecture; * S390 architecture; * User-Mode Linux (UML); * x86 architecture; * Block layer subsystem; * Cryptographic API; * Android drivers; * Serial ATA and Parallel ATA drivers; * ATM drivers; * Drivers core; * Null block device driver; * Ublk userspace block... --- 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-6.8.0-1002-gkeop](https://launchpad.net/ubuntu/+source/linux-signed-gkeop) –  [6.8.0-1002.4](https://launchpad.net/ubuntu/+source/linux-signed-gkeop/6.8.0-1002.4) | | | | [linux-image-gkeop](https://launchpad.net/ubuntu/+source/linux-meta-gkeop) –  [6.8.0-1002.4](https://launchpad.net/ubuntu/+source/linux-meta-gkeop/6.8.0-1002.4) | | | | [linux-image-gkeop-6.8](https://launchpad.net/ubuntu/+source/linux-meta-gkeop) –  [6.8.0-1002.4](https://launchpad.net/ubuntu/+source/linux-meta-gkeop/6.8.0-1002.4) | | | --- ### 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.
