Dist Ubuntu Esm H88
Updates to the Linux kernel in Ubuntu address various security vulnerabilities that pose serious risks to system integrity and operational stability.
Several security issues were fixed in the Linux kernel.

Summary

A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-gke: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-lowlatency: Linux low latency kernel - linux-oem-6.8: Linux kernel for OEM systems - linux-oracle: Linux kernel for Oracle Cloud systems Details: Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-23848) It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker co...

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1010-gke 6.8.0-1010.13 linux-image-6.8.0-1012-ibm 6.8.0-1012.12 linux-image-6.8.0-1012-oem 6.8.0-1012.12 linux-image-6.8.0-1012-oracle 6.8.0-1012.12 linux-image-6.8.0-1012-oracle-64k 6.8.0-1012.12 linux-image-6.8.0-1014-gcp 6.8.0-1014.16 linux-image-6.8.0-1015-aws 6.8.0-1015.16 linux-image-6.8.0-44-generic 6.8.0-44.44 linux-image-6.8.0-44-generic-64k 6.8.0-44.44 linux-image-6.8.0-44-lowlatency 6.8.0-44.44.1 linux-image-6.8.0-44-lowlatency-64k 6.8.0-44.44.1 linux-image-aws 6.8.0-1015.16 linux-image-gcp 6.8.0-1014.16 linux-image-generic 6.8.0-44.44 linux-image-generic-64k 6.8.0-44.44 linux-image-generic-64k-hwe-24.04 6.8.0-44.44 linux-image-generic-hwe-24.04 6.8.0-44.44 linux-image-generic-lpae 6.8.0-44.44 linux-image-gke 6.8.0-1010.13 linux-image-ibm 6.8.0-1012.12 linux-image-ibm-classic 6.8.0-1012.12 linux-image-ibm-lts-24.04 6.8.0-1012.12 linux-image-kvm 6.8.0-44.44 linux-image-lowlatency 6.8.0-44.44.1 linux-image-lowlatency-64k 6.8.0-44.44.1 linux-image-oracle 6.8.0-1012.12 linux-image-oracle-64k 6.8.0-1012.12 linux-image-virtual 6.8.0-44.44 linux-image-virtual-hwe-24.04 6.8.0-44.44 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.
