Ubuntu 24.04: Linux Kernel Important Data Leak Threat USN-7833-4

ubuntu
Calendar Grey October 31, 2025
Dist Ubuntu Esm H88
Multiple security fixes released for Ubuntu 24.04 LTS Linux kernel GCP to prevent potential data leakage and attacks.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-gcp-6.14: Linux kernel for Google Cloud Platform (GCP) systems

Details:

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos,

and Flavien Solt discovered that some AMD processors may allow an attacker

to infer data from previous stores, potentially resulting in the leakage of

privileged information. A local attacker could possibly use this to expose

sensitive information. (CVE-2024-36350, CVE-2024-36357)

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:

- ARM64 architecture;

- PowerPC architecture;

- RISC-V architecture;

- S390 architecture;

- x86 architecture;

- ACPI drivers;

- Serial ATA and Parallel ATA drivers;

- Drivers core;

- ATA over ethernet (AOE) driver;

- Ublk userspace block d...

Update Instructions

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

Ubuntu 24.04 LTS
   linux-image-6.14.0-1018-gcp     6.14.0-1018.19~24.04.1
   linux-image-6.14.0-1018-gcp-64k  6.14.0-1018.19~24.04.1
   linux-image-gcp                 6.14.0-1018.19~24.04.1
   linux-image-gcp-6.14            6.14.0-1018.19~24.04.1
   linux-image-gcp-64k             6.14.0-1018.19~24.04.1
   linux-image-gcp-64k-6.14        6.14.0-1018.19~24.04.1

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.
