A security issue affects these releases of Ubuntu and its derivatives:
=2D Ubuntu 18.04 LTS
=2D Ubuntu 16.04 LTS
=2D Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
=2D linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems
=2D linux-azure: Linux kernel for Microsoft Azure Cloud systems
Details:
Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2024-23848)
Attila Sz=C3=A1sz discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS
linux-image-4.15.0-1186-azure 4.15.0-1186.201
Available with Ubuntu Pro
linux-image-azure-lts-18.04 4.15.0.1186.154
Available with Ubuntu Pro
Ubuntu 16.04 LTS
linux-image-4.15.0-1186-azure 4.15.0-1186.201~16.04.1
Available with Ubuntu Pro
linux-image-azure 4.15.0.1186.201~16.04.1
Available with Ubuntu Pro
Ubuntu 14.04 LTS
linux-image-4.15.0-1186-azure 4.15.0-1186.201~14.04.1
Available with Ubuntu Pro
linux-image-azure 4.15.0.1186.201~14.04.1
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.
