--- title: 'USN-7383-1: 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-7383-1 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7383-1 --- # USN-7383-1: Linux kernel vulnerabilities Publication date 27 March 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](https://ubuntu.com/security/cves?package=linux) - Linux kernel * [linux-aws](https://ubuntu.com/security/cves?package=linux-aws) - Linux kernel for Amazon Web Services (AWS) systems * [linux-gcp](https://ubuntu.com/security/cves?package=linux-gcp) - Linux kernel for Google Cloud Platform (GCP) systems * [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-gkeop](https://ubuntu.com/security/cves?package=linux-gkeop) - Linux kernel for Google Container Engine (GKE) systems * [linux-lowlatency](https://ubuntu.com/security/cves?package=linux-lowlatency) - Linux low latency kernel * [linux-lowlatency-hwe-6.8](https://ubuntu.com/security/cves?package=linux-lowlatency-hwe-6.8) - Linux low latency kernel * [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 * [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; * x86 architecture; * Block layer subsystem; * Drivers core; * Ublk userspace block driver; * Compressed RAM block device driver; * CPU frequency scaling framework; * DAX dirext access to differentiated memory framework; * GPU drivers; * HID subsystem; * I3C subsystem; * IIO subsystem; * InfiniBand drivers; * IOMMU subsystem; * IRQ chip drivers; * Network drivers; * NTB driver; * Virtio pmem driver; * Parport drivers; * Pin controllers subsystem; * SCSI subsystem; * SuperH / SH-Mobile drivers; * Direct Digital Synthesis drivers; * Thermal drivers; * TTY drivers; * UFS... --- 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 |
