USN-7110-1: Linux kernel vulnerabilities

Publication date

14 November 2024

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

  • linux - Linux kernel
  • linux-aws - Linux kernel for Amazon Web Services (AWS) systems
  • linux-kvm - Linux kernel for cloud environments
  • linux-lts-xenial - Linux hardware enablement kernel from Xenial for Trusty

Details

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:

  • Cryptographic API;
  • HW tracing;
  • ISDN/mISDN subsystem;
  • Media drivers;
  • Network drivers;
  • SCSI drivers;
  • USB DSL drivers;
  • VFIO drivers;
  • Watchdog drivers;
  • JFS file system;
  • Amateur Radio drivers;
  • IPv4 networking;
  • IUCV driver;
  • TIPC protocol;
  • Integrity Measurement Architecture(IMA) framework;
  • SoC Audio for Freescale CPUs drivers;
  • USB sound devices

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

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