[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7460-1 --- # USN-7460-1: Linux kernel (Azure FIPS) vulnerabilities Publication date 24 April 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-azure-fips](https://ubuntu.com/security/cves?package=linux-azure-fips) - Linux kernel for Microsoft Azure Cloud systems with FIPS ## Details Jann Horn discovered that the watch\_queue event notification subsystem in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or escalate their privileges. ([CVE-2022-0995](https://ubuntu.com/security/CVE-2022-0995)) 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: * Network drivers; * Microsoft Azure Network Adapter (MANA) driver; * File systems infrastructure; * NTFS3 file system; * Ethernet bridge; * Ethtool driver; * IPv6 networking; * Network traffic control; * VMware vSockets driver ## 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-5.15.0-1087-azure-fips](https://launchpad.net/ubuntu/+source/linux-signed-azure-fips) –  5.15.0-1087.96+fips1   FIPS Updates | | | | [linux-image-azure-fips](https://launchpad.net/ubuntu/+source/linux-meta-azure-fips) –  5.15.0.1087.72   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.
