Ubuntu Security Notice USN-7184-1
January 06, 2025

linux-aws, linux-kvm vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

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;

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.
