A newly released exploit allows running Ubuntu on a PlayStation 5 and playing Steam games, but the hack works only on consoles with firmware versions 3.xx and 4.xx. Security engineer Andy Nguyen publicly released his ps5-linux-boot project, enabling users to transform older PS5 Phat models into Linux-based PC gaming devices.

“It turns your PS5 Phat console on 3.xx and 4.xx firmware into a fully functional Linux PC gaming device,” Nguyen announced in his project description. The hack is entirely unofficial and relies on a patched hypervisor vulnerability to give Linux direct access to the console’s hardware, including its eight Zen 2 CPU cores and 16 threads.

Background

The exploit targets a hypervisor vulnerability that Sony patched in later firmware versions. Nguyen’s project bypasses the PS5’s security layer, allowing Linux to run natively alongside the console’s operating system. While the exploit itself is not new, this is the first public release that streamlines the process for general users.

Similar projects have existed for the PS4, but this marks a significant step for the PS5 modding community. The release comes as Sony continues to enforce strict firmware updates to prevent such unauthorized access.

What This Means

For owners of older PS5 consoles, this opens the door to running a full desktop Linux environment and accessing the Steam library directly on the console. However, the limitation to outdated firmware means most current PS5 owners cannot take advantage of the exploit. Users who update their consoles to the latest version lose the ability to run Linux.

“This is a major achievement for the homebrew community, but Sony’s rapid patching means its impact is limited to a shrinking pool of consoles,” said Dr. Lynne Torres, a cybersecurity researcher specializing in game console exploits. “It highlights the ongoing cat-and-mouse game between Sony and modders.”

The project also raises concerns about potential security risks, as running an unofficial OS could expose the console to malware. Nguyen advises users to proceed at their own risk and only on secondary devices.

How to Access the Project

Nguyen’s ps5-linux-boot instructions are available on his GitHub repository, with detailed steps for formatting a USB drive and booting Ubuntu. The process requires no permanent hardware modifications, but users must stay on firmware 4.xx or lower.
