Kali Nethunter and Nexmon updates

Nexmon is a firmware Patching Framework for Broadcom and Cypress wi-fi chips that allows you to enable Monitor Mode and Frame Injection.

The Kali Team previously announced support for the Nexmon framework in July, enabling Raspberry Pi users to enjoy enhanced Wi-Fi features for security engagements.

With this release, Nexmon is now included in Kali Linux, making it more accessible to Raspberry Pi and other devices.

“In Kali 2025.1, we changed how we package our Raspberry Pi kernel, as well as bump to a new major version,” reads the Kali Linux 2025.3 announcement.

“Now Nexmon support is back as well as supporting Raspberry Pi 5! Other devices can also use Nexmon, its not limited to Raspberry Pis.”

In addition to Nexmon, Kali Nethunter has received some updates, including support for running it on the Samsung S10.

Kali NetHunter Car Hacking, CARsenal, has also received new features, including a new UI update and numerous bug fixes.

The Team says they will be releasing some videos in the future on how to CARsenal and demonstrating the various features.

Other changes

This release also includes other changes and improvements, including:

• The VPN IP panel plugin (Xfce) now allows you to specify the interface you are monitoring, to easily copy the IP address of your VPN connection to the clipboard.
• Kali is dropping support for ARMel (Acorn RISC Machine, Little-Endian).
• You can now install Kernel modules with Magisk. However, Kali warns it’s still in an experimental state.

How to get Kali Linux 2025.3

To start using Kali Linux 2025.3, you can upgrade your existing installation, select a platform, or directly download ISO images for new installs and live distributions.

For those updating from a previous version, you can use the following commands to upgrade to the latest version.
