USN-7039-1: Linux kernel vulnerabilities

Publication date

26 September 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:

  • GPU drivers;
  • Input Device (Tablet) drivers;
  • Modular ISDN driver;
  • Multiple devices driver;
  • Network drivers;
  • Near Field Communication (NFC) drivers;
  • SCSI drivers;
  • GCT GDM724x LTE driver;
  • USB subsystem;
  • VFIO drivers;
  • GFS2 file system;
  • JFS file system;
  • NILFS2 file system;
  • Networking core;
  • IPv4 networking;
  • L2TP protocol;
  • Netfilter;
  • RxRPC session sockets

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:
