Ubuntu 22.04 LTS: USN-6917-1 Critical: Linux Kernel Issues Fixed

ubuntu
Calendar Grey July 26, 2024
Dist Ubuntu Esm H88
Ubuntu Security Notice USN-6918-2 addresses resolution for multiple kernel vulnerabilities, improving overall system reliability and protective measures.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-azure: Linux kernel for Microsoft Azure Cloud systems

- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems

- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems

- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems

Details:

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not

properly handle certain error conditions, leading to a NULL pointer

dereference. A local attacker could possibly trigger this vulnerability to

cause a denial of service. (CVE-2022-38096)

Gui-Dong Han discovered that the software RAID driver in the Linux kernel

contained a race condition, leading to an integer overflow vulnerability. A

privileged attacker could possibly use this to cause a denial of service

(system crash). (CVE-2024-23307)

It was discovered that a race condition existed in the Bluetooth subsystem

in the Linux kernel when modifying ce...

Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1068-azure   5.15.0-1068.77
  linux-image-5.15.0-1068-azure-fde  5.15.0-1068.77.1
  linux-image-azure-fde-lts-22.04  5.15.0.1068.77.45
  linux-image-azure-lts-22.04     5.15.0.1068.66

Ubuntu 20.04 LTS
  linux-image-5.15.0-1068-azure   5.15.0-1068.77~20.04.1
  linux-image-5.15.0-1068-azure-fde  5.15.0-1068.77~20.04.1.1
  linux-image-azure               5.15.0.1068.77~20.04.1
  linux-image-azure-cvm           5.15.0.1068.77~20.04.1
  linux-image-azure-fde           5.15.0.1068.77~20.04.1.45

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.
