Summary

A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-oracle-6.8: Linux kernel for Oracle Cloud systems Details: It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information. (CVE-2025-2312) 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: - GPIO subsystem; - GPU drivers; - InfiniBand drivers; - IRQ chip drivers; - Network drivers; - Mellanox network drivers; - i.MX PM domains; - SCSI subs...

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1027-oracle 6.8.0-1027.28 linux-image-6.8.0-1027-oracle-64k 6.8.0-1027.28 linux-image-6.8.0-1029-raspi 6.8.0-1029.33 linux-image-oracle 6.8.0-1027.28 linux-image-oracle-64k 6.8.0-1027.28 linux-image-oracle-64k-lts-24.04 6.8.0-1027.28 linux-image-oracle-lts-24.04 6.8.0-1027.28 linux-image-raspi 6.8.0-1029.33 Ubuntu 22.04 LTS linux-image-6.8.0-1027-oracle 6.8.0-1027.28~22.04.1 linux-image-6.8.0-1027-oracle-64k 6.8.0-1027.28~22.04.1 linux-image-oracle 6.8.0-1027.28~22.04.1 linux-image-oracle-64k 6.8.0-1027.28~22.04.1 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.
