USN-7185-1: Linux kernel vulnerabilities

Publication date

6 January 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

  • linux - Linux kernel
  • linux-aws - Linux kernel for Amazon Web Services (AWS) systems
  • linux-aws-hwe - Linux kernel for Amazon Web Services (AWS-HWE) systems
  • linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
  • linux-gcp-4.15 - Linux kernel for Google Cloud Platform (GCP) systems
  • linux-hwe - Linux hardware enablement (HWE) kernel
  • linux-kvm - Linux kernel for cloud environments
  • linux-oracle - Linux kernel for Oracle Cloud systems

Details

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux
kernel contained an integer overflow vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2022-36402)

Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver
in the Linux kernel during device removal. A privileged attacker could use
this to cause a denial of service (system crash). (CVE-2023-35827)

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:

  • GPU drivers;
  • I2C subsystem;
  • InfiniBand drivers;
  • IRQ chip drivers;
  • Network drivers;
  • Pin controllers subsystem;
  • S/390 drivers;
  • TTY drivers;
  • USB Host Controller...

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

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