Ubuntu Security Notice USN-7120-3
November 21, 2024
linux-lowlatency, linux-lowlatency-hwe-6.8 vulnerabilities
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-lowlatency: Linux low latency kernel
- linux-lowlatency-hwe-6.8: Linux low latency kernel
Details:
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 following
package versions:
Ubuntu 24.04 LTS
linux-image-6.8.0-49-lowlatency 6.8.0-49.49.1
linux-image-6.8.0-49-lowlatency-64k 6.8.0-49.49.1
linux-image-lowlatency 6.8.0-49.49.1
linux-image-lowlatency-64k 6.8.0-49.49.1
linux-image-lowlatency-64k-hwe-24.04 6.8.0-49.49.1
linux-image-lowlatency-hwe-24.04 6.8.0-49.49.1
Ubuntu 22.04 LTS
linux-image-6.8.0-49-lowlatency 6.8.0-49.49.1~22.04.1
linux-image-6.8.0-49-lowlatency-64k 6.8.0-49.49.1~22.04.1
linux-image-lowlatency-64k-hwe-22.04 6.8.0-49.49.1~22.04.1
linux-image-lowlatency-hwe-22.04 6.8.0-49.49.1~22.04.1
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.
