Ubuntu Security Notice USN-7009-1
September 13, 2024

linux-azure, linux-azure-5.15, linux-azure-fde 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-fde: Linux kernel for Microsoft Azure CVM cloud systems
- linux-azure-5.15: 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)

Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel
did not properly check for the device to be enabled before writing. A local
attacker could possibly use this to cause a denial of service.
(CVE-2024-25741)

It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash). (CVE-2024-40902)

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 22.04 LTS
  linux-image-5.15.0-1072-azure   5.15.0-1072.81
  linux-image-5.15.0-1072-azure-fde  5.15.0-1072.81.1
  linux-image-azure-fde-lts-22.04  5.15.0.1072.81.49
  linux-image-azure-lts-22.04     5.15.0.1072.70

Ubuntu 20.04 LTS
  linux-image-5.15.0-1072-azure   5.15.0-1072.81~20.04.1
  linux-image-azure               5.15.0.1072.81~20.04.1
  linux-image-azure-cvm           5.15.0.1072.81~20.04.1

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.
