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.

linux-azure vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
Details:
Siebe Devroe, Héloïse Gollier, and Mathy Vanhoef discovered that the WiFi
implementation in the Linux kernel did not properly handle aggregated
frames in mesh networks, due to an incorrect fix for CVE-2020-24588. A
physically proximate attacker could use this issue to inject packets.
(CVE-2025-27558)
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP
subsystem in the Linux kernel when handling socket buffer fragments. This
flaw is known as Fragnesia. A local attacker could use this to escalate
privileges, or possibly escape a container. (CVE-2026-43503)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS
linux-image-4.15.0-1205-azure 4.15.0-1205.220~14.04.1
Available with Ubuntu Pro
linux-image-azure 4.15.0.1205.220~14.04.1
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.

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.
