Ubuntu 24.04 LTS USN-6999-1 Critical: Kernel Security Flaws

ubuntu
Calendar Grey September 11, 2024
Scroller Ubuntu
Updates to the Linux kernel in Ubuntu address various security vulnerabilities that pose serious risks to system integrity and operational stability.
Several security issues were fixed in the Linux kernel.

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 we...

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.
