========================================================================== Ubuntu Security Notice USN-7791-4 October 14, 2025
linux-oracle, linux-oracle-6.14 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 25.04 - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oracle: Linux kernel for Oracle Cloud systems - linux-oracle-6.14: Linux kernel for Oracle 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: - Packet sockets; - Network traffic control; - VMware vSockets driver; - XFRM subsystem; (CVE-2025-38477, CVE-2025-38618, CVE-2025-38500, CVE-2025-38617) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 25.04 linux-image-6.14.0-1014-oracle 6.14.0-1014.14 linux-image-6.14.0-1014-oracle-64k 6.14.0-1014.14 linux-image-oracle 6.14.0-1014.14 linux-image-oracle-6.14 6.14.0-1014.14 linux-image-oracle-64k 6.14.0-1014.14 linux-image-oracle-64k-6.14 6.14.0-1014.14 Ubuntu 24.04 LTS linux-image-6.14.0-1014-oracle 6.14.0-1014.14~24.04.1 linux-image-6.14.0-1014-oracle-64k 6.14.0-1014.14~24.04.1 linux-image-oracle 6.14.0-1014.14~24.04.1 linux-image-oracle-6.14 6.14.0-1014.14~24.04.1 linux-image-oracle-64k 6.14.0-1014.14~24.04.1 linux-image-oracle-64k-6.14 6.14.0-1014.14~24.04.1 After a standard system update you need to reboot your computer to make all the necessary changes. 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.
