Ubuntu Security Notice USN-6870-1
July 04, 2024
linux-aws, linux-azure, linux-azure-5.15, linux-azure-fde,
linux-azure-fde-5.15, linux-gke, linux-gkeop, linux-gkeop-5.15, linux-ibm,
linux-intel-iotg, linux-intel-iotg-5.15, linux-kvm, linux-oracle,
linux-oracle-5.15 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems
- linux-gke: Linux kernel for Google Container Engine (GKE) systems
- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-intel-iotg: Linux kernel for Intel IoT platforms
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems
- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems
- linux-gkeop-5.15: Linux kernel for Google Container Engine (GKE) systems
- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms
- linux-oracle-5.15: Linux kernel for Oracle Cloud systems
Details:
It was discovered that the Intel Data Streaming and Intel Analytics
Accelerator drivers in the Linux kernel allowed direct access to the
devices for unprivileged users and virtual machines. A local attacker could
use this to cause a denial of service. (CVE-2024-21823)
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 subsystem:
- Netfilter;
(CVE-2024-26643, CVE-2024-26924)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:

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.
