[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7294-3 --- # USN-7294-3: Linux kernel vulnerabilities Publication date 28 February 2025 Overview Several security issues were fixed in the Linux kernel. Releases [20.04 LTS](https://ubuntu.com/security/notices?release=focal) --- Open side navigation ## Packages * [linux-ibm](https://ubuntu.com/security/cves?package=linux-ibm) - Linux kernel for IBM 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; * Block layer subsystem; * ACPI drivers; * Drivers core; * ATA over ethernet (AOE) driver; * TPM device driver; * GPIO subsystem; * GPU drivers; * HID subsystem; * I2C subsystem; * InfiniBand drivers; * Mailbox framework; * Multiple devices driver; * Media drivers; * Network drivers; * NTB driver; * Virtio pmem driver; * Parport drivers; * PCI subsystem; * SPI subsystem; * Direct Digital Synthesis drivers; * USB Device Class drivers; * USB Dual Role (OTG-ready) Controller drivers; * USB Serial drivers; * USB Type-C support driver; * Framebuffer layer; * BTRFS file... --- 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 | | --- | --- | | 20.04 LTS focal | [linux-image-5.4.0-1086-ibm](https://launchpad.net/ubuntu/+source/linux-signed-ibm) –  [5.4.0-1086.91](https://launchpad.net/ubuntu/+source/linux-signed-ibm/5.4.0-1086.91) | | | | [linux-image-ibm-lts-20.04](https://launchpad.net/ubuntu/+source/linux-meta-ibm) –  [5.4.0.1086.115](https://launchpad.net/ubuntu/+source/linux-meta-ibm/5.4.0.1086.115) | | | --- ### 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.
