==========================================================================Ubuntu Security Notice USN-7120-2November 20, 2024linux-aws-6.8, linux-azure, linux-azure-6.8, linux-oracle-6.8,vulnerabilities==========================================================================A security issue affects these releases of Ubuntu and its derivatives:- Ubuntu 24.04 LTS- Ubuntu 22.04 LTSSummary:Several security issues were fixed in the Linux kernel.Software Description:- linux-azure: Linux kernel for Microsoft Azure Cloud systems- linux-aws-6.8: Linux kernel for Amazon Web Services (AWS) systems- linux-azure-6.8: Linux kernel for Microsoft Azure cloud systems- linux-oracle-6.8: Linux kernel for Oracle Cloud systemsDetails: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: - File systems infrastructure; - Network traffic control;(CVE-2024-46800, CVE-2024-43882)Update instructions:The problem can be corrected by updating your system to the followingpackage versions:Ubuntu 24.04 LTS linux-image-6.8.0-1018-azure 6.8.0-1018.21 linux-image-6.8.0-1018-azure-fde 6.8.0-1018.21 linux-image-azure 6.8.0-1018.21 linux-image-azure-fde 6.8.0-1018.21Ubuntu 22.04 LTS linux-image-6.8.0-1016-oracle 6.8.0-1016.17~22.04.1 linux-image-6.8.0-1016-oracle-64k 6.8.0-1016.17~22.04.1 linux-image-6.8.0-1018-azure 6.8.0-1018.21~22.04.1 linux-image-6.8.0-1018-azure-fde 6.8.0-1018.21~22.04.1 linux-image-6.8.0-1019-aws 6.8.0-1019.21~22.04.1 linux-image-aws 6.8.0-1019.21~22.04.1 linux-image-azure 6.8.0-1018.21~22.04.1 linux-image-azure-fde 6.8.0-1018.21~22.04.1 linux-image-oracle 6.8.0-1016.17~22.04.1 linux-image-oracle-64k 6.8.0-1016.17~22.04.1After a standard system update you need to reboot your computer to makeall the necessary changes.ATTENTION: Due to an unavoidable ABI change the kernel updates havebeen given a new version number, which requires you to recompile andreinstall 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 performthis as well.References: https://ubuntu.com/security/notices/USN-7120-2 https://ubuntu.com/security/notices/USN-7120-1 CVE-2024-43882, CVE-2024-46800Package Information: https://launchpad.net/ubuntu/+source/linux-azure/6.8.0-1018.21 https://launchpad.net/ubuntu/+source/linux-aws-6.8/6.8.0-1019.21~22.04.1 https://launchpad.net/ubuntu/+source/linux-azure-6.8/6.8.0-1018.21~22.04.1 https://launchpad.net/ubuntu/+source/linux-oracle-6.8/6.8.0-1016.17~22.04.1Related news
Ubuntu Security Notice 7123-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.
