Ubuntu Security Notice USN-7076-1
October 17, 2024

linux-azure, linux-azure-5.15 vulnerabilities
==========================================================================

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-azure-5.15: Linux kernel for Microsoft Azure 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-2024-27397, CVE-2024-45016, CVE-2024-45001, CVE-2024-38630)

Update instructions:

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1074-azure   5.15.0-1074.83
   linux-image-azure-lts-22.04     5.15.0.1074.72

Ubuntu 20.04 LTS
   linux-image-5.15.0-1074-azure   5.15.0-1074.83~20.04.1
   linux-image-azure               5.15.0.1074.83~20.04.1
   linux-image-azure-cvm           5.15.0.1074.83~20.04.1

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.
