--- title: 'USN-8029-1: 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-8029-1 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-8029-1 --- # USN-8029-1: Linux kernel vulnerabilities Publication date 12 February 2026 Overview Several security issues were fixed in the Linux kernel. Releases [25.10](https://ubuntu.com/security/notices?release=questing) --- Open side navigation ## Packages * [linux](https://ubuntu.com/security/cves?package=linux) - Linux kernel * [linux-raspi](https://ubuntu.com/security/cves?package=linux-raspi) - Linux kernel for Raspberry Pi systems * [linux-realtime](https://ubuntu.com/security/cves?package=linux-realtime) - Linux kernel for Real-time 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; * MIPS architecture; * Nios II architecture; * PA-RISC architecture; * RISC-V architecture; * S390 architecture; * Sun Sparc architecture; * x86 architecture; * Xtensa architecture; * Block layer subsystem; * Cryptographic API; * Compute Acceleration Framework; * ACPI drivers; * Drivers core; * Network block device driver; * Bluetooth drivers; * Bus devices; * Hardware random number generator core; * Character device driver; * Clock framework and drivers; * Data acquisition framework and drivers; * CPU frequency scaling framework; * Hardware crypto device drivers; * CXL (Compute Express Link)... --- 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 | | --- | --- | | 25.10 questing | [linux-image-6.17.0-1006-realtime](https://launchpad.net/ubuntu/+source/linux-signed-realtime) –  [6.17.0-1006.7](https://launchpad.net/ubuntu/+source/linux-signed-realtime/6.17.0-1006.7) | | | | [linux-image-6.17.0-1008-raspi](https://launchpad.net/ubuntu/+source/linux-raspi) –  [6.17.0-1008.8](https://launchpad.net/ubuntu/+source/linux-raspi/6.17.0-1008.8) | | | | [linux-image-6.17.0-14-generic](https://launchpad.net/ubuntu/+source/linux-signed) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-signed/6.17.0-14.14) | | | | [linux-image-6.17.0-14-generic-64k](https://launchpad.net/ubuntu/+source/linux-signed) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-signed/6.17.0-14.14) | | | | [linux-image-generic](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | | [linux-image-generic-6.17](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | | [linux-image-generic-64k](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | | [linux-image-generic-64k-6.17](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | | [linux-image-raspi](https://launchpad.net/ubuntu/+source/linux-meta-raspi) –  [6.17.0-1008.8](https://launchpad.net/ubuntu/+source/linux-meta-raspi/6.17.0-1008.8) | | | | [linux-image-raspi-6.17](https://launchpad.net/ubuntu/+source/linux-meta-raspi) –  [6.17.0-1008.8](https://launchpad.net/ubuntu/+source/linux-meta-raspi/6.17.0-1008.8) | | | | [linux-image-realtime](https://launchpad.net/ubuntu/+source/linux-meta-realtime) –  [6.17.0-1006.7](https://launchpad.net/ubuntu/+source/linux-meta-realtime/6.17.0-1006.7) | | | | [linux-image-realtime-6.17](https://launchpad.net/ubuntu/+source/linux-meta-realtime) –  [6.17.0-1006.7](https://launchpad.net/ubuntu/+source/linux-meta-realtime/6.17.0-1006.7) | | | | [linux-image-virtual](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | | [linux-image-virtual-6.17](https://launchpad.net/ubuntu/+source/linux-meta) –  [6.17.0-14.14](https://launchpad.net/ubuntu/+source/linux-meta/6.17.0-14.14) | | | --- ### 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.
