Ubuntu Security Notice USN-6999-1
September 11, 2024

linux, linux-aws, linux-gcp, linux-gke, linux-ibm, linux-lowlatency,
linux-oem-6.8, linux-oracle vulnerabilities
==========================================================================

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

– Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
– linux: Linux kernel
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
– linux-gke: Linux kernel for Google Container Engine (GKE) systems
– linux-ibm: Linux kernel for IBM cloud systems
– linux-lowlatency: Linux low latency kernel
– linux-oem-6.8: Linux kernel for OEM systems
– linux-oracle: Linux kernel for Oracle 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)

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.

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.
