[USN-6211-1] Linux kernel (Azure) regression
==========================================================================
Ubuntu Security Notice USN-6211-1
July 07, 2023
linux-azure regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS (Available with Ubuntu Pro)
Summary:
The system could show undesired warning messages in certain conditions.
Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
Details:
USN-6130-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that
update introduced a spurious warning in the IPv6 subsystem. This update
removes the undesired warning message.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS (Available with Ubuntu Pro):
linux-image-4.15.0-1167-azure 4.15.0-1167.182~14.04.1
linux-image-azure 4.15.0.1167.133
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.
