USN-7088-1: Linux kernel vulnerabilities

Publication date

31 October 2024

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

  • linux - Linux kernel
  • linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
  • linux-gcp-5.4 - Linux kernel for Google Cloud Platform (GCP) systems
  • linux-gkeop - Linux kernel for Google Container Engine (GKE) 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)

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:

  • ARM64 architecture;
  • PowerPC architecture;
  • User-Mode Linux (UML);
  • x86 architecture;
  • Block layer subsystem;
  • Cryptographic API;
  • Android drivers;
  • Serial ATA and Parallel ATA drivers;
  • ATM drivers;
  • Drivers core;
  • CPU frequency scaling framework;
  • Device frequency scaling framework;
  • GPU drivers;
  • HID subsystem;
  • Hardware monitoring drivers;
  • InfiniBand drivers;
  • Input Device core...

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:
