ubuntu
Calendar Grey January 6, 2025
Dist Ubuntu Esm H88
Various security patches have been released for the Linux kernel in Ubuntu to fix essential system flaws.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-kvm: Linux kernel for cloud environments

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;

- Network drivers;

- Pin controllers subsystem;

- TTY drivers;

- USB Mass Storage drivers;

- F...

Update Instructions

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

Ubuntu 16.04 LTS
   linux-image-4.4.0-1140-kvm      4.4.0-1140.151
                                   Available with Ubuntu Pro
   linux-image-4.4.0-1177-aws      4.4.0-1177.192
                                   Available with Ubuntu Pro
   linux-image-aws                 4.4.0.1177.181
                                   Available with Ubuntu Pro
   linux-image-kvm                 4.4.0.1140.137
                                   Available with Ubuntu Pro

Ubuntu 14.04 LTS
   linux-image-4.4.0-1139-aws      4.4.0-1139.145
                                   Available with Ubuntu Pro
   linux-image-aws                 4.4.0.1139.136
                                   Available with Ubuntu Pro

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.
