USN-7088-2: Linux kernel vulnerabilities

Publication date

4 November 2024

Overview

Several security issues were fixed in the Linux kernel.

Packages

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...

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:

Ubuntu Release Package Version
20.04 focal linux-image-5.4.0-1094-bluefield –  5.4.0-1094.101
linux-image-5.4.0-1139-azure –  5.4.0-1139.146
linux-image-azure-lts-20.04 –  5.4.0.1139.133
linux-image-bluefield –  5.4.0.1094.90
