USN-7455-1: Linux kernel vulnerabilities

Publication date

24 April 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

Jann Horn discovered that the watch_queue event notification subsystem in
the Linux kernel contained an out-of-bounds write vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
escalate their privileges. (CVE-2022-0995)

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:

  • Network drivers;
  • File systems infrastructure;
  • NTFS3 file system;
  • Ethernet bridge;
  • Ethtool driver;
  • IPv6 networking;
  • Network traffic control;
  • VMware vSockets driver

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:
