Ubuntu 24.04 LTS USN-6893-1 Critical Kernel Denial of Service Fixes

ubuntu
Calendar Grey July 11, 2024
Dist Ubuntu Esm H88
A series of critical security patches for the Linux kernel in Ubuntu have mitigated significant risks, which encompass potential denial of service flaws.
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-azure: Linux kernel for Microsoft Azure Cloud systems

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

- linux-ibm: Linux kernel for IBM cloud systems

- linux-intel: Linux kernel for Intel IoT platforms

- linux-lowlatency: Linux low latency kernel

- linux-oem-6.8: Linux kernel for OEM systems

- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

It was discovered that a race condition existed in the Bluetooth subsystem

in the Linux kernel when modifying certain settings values through debugfs.

A privileged local attacker could use this to cause a denial of service.

(CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

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;

- RISC-V architecture;

- S390 ...

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.
