linux-aws, linux-gcp, linux-hwe-6.11, linux-oracle, linux-raspi,
linux-realtime vulnerabilities

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

=2D Ubuntu 24.10
=2D Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
=2D linux-aws: Linux kernel for Amazon Web Services (AWS) systems
=2D linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
=2D linux-oracle: Linux kernel for Oracle Cloud systems
=2D linux-raspi: Linux kernel for Raspberry Pi systems
=2D linux-realtime: Linux kernel for Real-time systems
=2D linux-hwe-6.11: Linux hardware enablement (HWE) kernel

Details:

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)

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:
  - Block layer subsystem;
  - Networking core;
(CVE-2024-56672, CVE-2024-56658)

Update instructions:

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

Ubuntu 24.10
  linux-image-6.11.0-1006-realtime  6.11.0-1006.6
  linux-image-6.11.0-1009-raspi   6.11.0-1009.9
  linux-image-6.11.0-1010-aws     6.11.0-1010.11
  linux-image-6.11.0-1010-gcp     6.11.0-1010.10
  linux-image-6.11.0-1012-oracle  6.11.0-1012.13
  linux-image-6.11.0-1012-oracle-64k  6.11.0-1012.13
  linux-image-aws                 6.11.0-1010.11
  linux-image-gcp                 6.11.0-1010.10
  linux-image-oracle              6.11.0-1012.13
  linux-image-oracle-64k          6.11.0-1012.13
  linux-image-raspi               6.11.0-1009.9
  linux-image-realtime            6.11.0-1006.6

Ubuntu 24.04 LTS
  linux-image-6.11.0-19-generic   6.11.0-19.19~24.04.1
  linux-image-6.11.0-19-generic-64k  6.11.0-19.19~24.04.1
  linux-image-generic-64k-hwe-24.04  6.11.0-19.19~24.04.1
  linux-image-generic-hwe-24.04   6.11.0-19.19~24.04.1
  linux-image-virtual-hwe-24.04   6.11.0-19.19~24.04.1

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.
