[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7511-2 --- # USN-7511-2: Linux kernel (GCP FIPS) vulnerabilities Publication date 16 May 2025 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux-gcp-fips](https://ubuntu.com/security/cves?package=linux-gcp-fips) - Linux kernel for Google Cloud Platform (GCP) systems with FIPS ## 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; * Block layer subsystem; * Network block device driver; * Bus devices; * Character device driver; * TPM device driver; * Clock framework and drivers; * GPIO subsystem; * GPU drivers; * HID subsystem; * I2C subsystem; * InfiniBand drivers; * Media drivers; * NVIDIA Tegra memory controller driver; * Network drivers; * PCI subsystem; * PPS (Pulse Per Second) driver; * PTP clock framework; * RapidIO drivers; * Real Time Clock drivers; * SLIMbus drivers; * QCOM SoC drivers; * Trusted Execution Environment drivers; * TTY drivers; * USB DSL... --- 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 | | --- | --- | | 22.04 LTS jammy | [linux-image-5.15.0-1083-gcp-fips](https://launchpad.net/ubuntu/+source/linux-signed-gcp-fips) –  5.15.0-1083.92+fips1   FIPS Updates | | | | [linux-image-gcp-fips](https://launchpad.net/ubuntu/+source/linux-meta-gcp-fips) –  5.15.0.1083.73   FIPS Updates | | | --- ### 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.
