ubuntu

March 5, 2025

Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

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

- linux-oracle: Linux kernel for Oracle Cloud systems

- linux-raspi: Linux kernel for Raspberry Pi systems

- linux-realtime: Linux kernel for Real-time systems

- linux-hwe-6.11: Linux hardware enablement (HWE) kernel

Details:

Attila Szász 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;

...

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.
