This update corrects flaws in the following subsystems: Cryptographic API; Unix domain sockets 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: Cryptographic API; Unix domain sockets 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. 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-6.17.0-1005-realtime – 6.17.0-1005.6 linux-image-6.17.0-1006-aws – 6.17.0-1006.6 linux-image-6.17.0-1006-aws-64k – 6.17.0-1006.6 linux-image-6.17.0-1006-gcp – 6.17.0-1006.6 linux-image-6.17.0-1006-gcp-64k – 6.17.0-1006.6 linux-image-6.17.0-1006-oracle – 6.17.0-1006.6 linux-image-6.17.0-1006-oracle-64k – 6.17.0-1006.6 linux-image-6.17.0-1007-azure – 6.17.0-1007.7 linux-image-6.17.0-1007-raspi – 6.17.0-1007.7 linux-image-6.17.0-12-generic – 6.17.0-12.12 linux-image-6.17.0-12-generic-64k – 6.17.0-12.12 linux-image-aws – 6.17.0-1006.6 linux-image-aws-6.17 – 6.17.0-1006.6 linux-image-aws-64k – 6.17.0-1006.6 linux-image-aws-64k-6.17 – 6.17.0-1006.6 linux-image-azure – 6.17.0-1007.7 linux-image-azure-6.17 – 6.17.0-1007.7 linux-image-gcp – 6.17.0-1006.6 linux-image-gcp-6.17 – 6.17.0-1006.6 linux-image-gcp-64k – 6.17.0-1006.6 linux-image-gcp-64k-6.17 – 6.17.0-1006.6 linux-image-generic – 6.17.0-12.12 linux-image-generic-6.17 – 6.17.0-12.12 linux-image-generic-64k – 6.17.0-12.12 linux-image-generic-64k-6.17 – 6.17.0-12.12 linux-image-oracle – 6.17.0-1006.6 linux-image-oracle-6.17 – 6.17.0-1006.6 linux-image-oracle-64k – 6.17.0-1006.6 linux-image-oracle-64k-6.17 – 6.17.0-1006.6 linux-image-raspi – 6.17.0-1007.7 linux-image-raspi-6.17 – 6.17.0-1007.7 linux-image-realtime – 6.17.0-1005.6 linux-image-realtime-6.17 – 6.17.0-1005.6 linux-image-virtual – 6.17.0-12.12 linux-image-virtual-6.17 – 6.17.0-12.12 24.04 LTS noble linux-image-6.17.0-1010-oem – 6.17.0-1010.10 linux-image-oem-24.04d – 6.17.0-1010.10 linux-image-oem-6.17 – 6.17.0-1010.10 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.
