Ubuntu Security Notices USN-7835-5 USN-7835-5: Linux kernel (Oracle) vulnerabilities Publication date 6 November 2025 Overview Several security issues were fixed in the Linux kernel. Releases 22.04 LTS Packages linux-oracle-6.8 - 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: ARM64 architecture; PowerPC architecture; x86 architecture; ACPI drivers; Ublk userspace block driver; Clock framework and drivers; GPU drivers; IIO subsystem; InfiniBand drivers; Media drivers; MemoryStick subsystem; Network drivers; NTB driver; PCI subsystem; Remote Processor subsystem; Thermal drivers; Virtio Host (VHOST) subsystem; 9P distributed file system; File systems infrastructure; JFS file system; Network file system (NFS) server daemon; NTFS3 file system; SMB network file system; Memory management; RDMA verbs API; Kernel fork()...

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 22.04 LTS jammy linux-image-6.8.0-1038-oracle – 6.8.0-1038.39~22.04.1 linux-image-6.8.0-1038-oracle-64k – 6.8.0-1038.39~22.04.1 linux-image-oracle – 6.8.0-1038.39~22.04.1 linux-image-oracle-6.8 – 6.8.0-1038.39~22.04.1 linux-image-oracle-64k – 6.8.0-1038.39~22.04.1 linux-image-oracle-64k-6.8 – 6.8.0-1038.39~22.04.1 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.
