USN-7185-2: Linux kernel (Azure) vulnerabilities

Publication date

9 January 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

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)

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:

Ubuntu Release Package Version
18.04 bionic linux-image-4.15.0-1184-azure –  4.15.0-1184.199  
linux-image-azure-lts-18.04 –  4.15.0.1184.152  
16.04 xenial linux-image-4.15.0-1184-azure –  4.15.0-1184.199~16.04.1  
linux-image-azure –  4.15.0.1184.199~16.04.1  
14.04 trusty linux-image-4.15.0-1184-azure –  4.15.0-1184.199~14.04.1  
linux-image-azure –  4.15.0.1184.199~14.04.1
