USN-6864-1: Linux kernel vulnerabilities
4 July 2024
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
- linux-intel - Linux kernel for Intel IoT platforms
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)
A security issue was discovered in the Linux kernel.
An attacker could possibly use it to compromise the system.
This update corrects flaws in the following subsystem:
- Netfilter;
(CVE-2024-26924)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 24.04
-
linux-image-6.8.0-1006-intel
-
6.8.0-1006.13
-
linux-image-6.8.0-1009-gcp
-
6.8.0-1009.10
-
linux-image-gcp
-
6.8.0-1009.10
-
linux-image-intel
-
6.8.0-1006.13
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.
