USN-7089-2: Linux kernel vulnerabilities

USN-7089-2: Linux kernel vulnerabilities
4 November 2024

Several security issues were fixed in the Linux kernel.

Releases
Ubuntu 24.04 LTS

Packages
linux-azure - Linux kernel for Microsoft Azure Cloud systems
linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
linux-ibm - Linux kernel for IBM cloud systems

Details
Chenyuan Yang discovered that the USB Gadget subsystem in the Linux
kernel did not properly check for the device to be enabled before
writing. A local attacker could possibly use this to cause a denial of
service. (CVE-2024-25741)

Update instructions
The problem can be corrected by updating your system to the following package versions:

Ubuntu 24.04

• linux-image-6.8.0-1014-ibm - 6.8.0-1014.14
• linux-image-6.8.0-1016-azure - 6.8.0-1016.18
• linux-image-6.8.0-1016-azure-fde - 6.8.0-1016.18
• linux-image-6.8.0-1016-gcp - 6.8.0-1016.18
• linux-image-azure - 6.8.0-1016.18
• linux-image-azure-fde - 6.8.0-1016.18
• linux-image-gcp - 6.8.0-1016.18
• linux-image-ibm - 6.8.0-1014.14
• linux-image-ibm-classic - 6.8.0-1014.14
• linux-image-ibm-lts-24.04 - 6.8.0-1014.14

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.
