linux-azure-fde-5.15 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems
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:
  - Microsoft Azure Network Adapter (MANA) driver;
  - Watchdog drivers;
  - Netfilter;
  - Network traffic control;
(CVE-2024-45016, CVE-2024-38630, CVE-2024-45001, CVE-2024-27397)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
  linux-image-5.15.0-1074-azure-fde  5.15.0-1074.83~20.04.1.1
  linux-image-azure-fde           5.15.0.1074.83~20.04.1.51
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.
