--- title: 'USN-7835-3: 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-7835-3 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7835-3 --- # USN-7835-3: Linux kernel vulnerabilities Publication date 22 October 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-gcp-6.8](https://ubuntu.com/security/cves?package=linux-gcp-6.8) - Linux kernel for Google Cloud Platform (GCP) systems * [linux-gke](https://ubuntu.com/security/cves?package=linux-gke) - Linux kernel for Google Container Engine (GKE) systems * [linux-nvidia](https://ubuntu.com/security/cves?package=linux-nvidia) - Linux kernel for NVIDIA systems * [linux-nvidia-6.8](https://ubuntu.com/security/cves?package=linux-nvidia-6.8) - Linux kernel for NVIDIA systems * [linux-nvidia-lowlatency](https://ubuntu.com/security/cves?package=linux-nvidia-lowlatency) - Linux low latency kernel for NVIDIA 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; * ACPI drivers; * Ublk userspace block driver; * Clock framework and drivers; * GPU drivers; * IIO subsystem; * InfiniBand drivers; * Media drivers; * MemoryStick subsystem; * Network drivers; * NTB driver; * PCI subsystem; * Remote Processor subsystem; * Thermal drivers; * Virtio Host (VHOST) subsystem; * 9P distributed file system; * File systems infrastructure; * JFS file system; * Network file system (NFS) server daemon; * NTFS3 file system; * SMB network file system; * Memory management; * RDMA verbs API; * Kernel fork()... --- 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 |
