Ubuntu Security Notice USN-7262-2
February 24, 2025

linux-kvm vulnerabilities
==========================================================================

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

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-kvm: Linux kernel for cloud environments

Details:

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:
- Multiple devices driver;
- Network drivers;
- Sonic Silicon Backplane drivers;
- File systems infrastructure;
- Closures library;
- Netfilter;
(CVE-2024-41012, CVE-2024-38597, CVE-2024-42252, CVE-2024-43914,
CVE-2024-38553, CVE-2024-40982, CVE-2024-41066, CVE-2024-42311,
CVE-2024-41020, CVE-2024-53141)

Update instructions:

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

Ubuntu 16.04 LTS
linux-image-4.4.0-1141-kvm 4.4.0-1141.152
Available with Ubuntu Pro
linux-image-kvm 4.4.0.1141.138
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.
