Breaking News — A security engineer has released a public tool that boots Ubuntu on a PlayStation 5 and runs Steam games, but only on consoles with outdated firmware. Andy Nguyen, the researcher behind the exploit, announced the ps5-linux-boot project this week, enabling owners of PS5 Phat models on firmware versions 3.xx and 4.xx to transform their console into a Linux PC gaming device.
"This is a fully functional Linux environment with direct hardware access," Nguyen said in a statement. "Users can install Steam and play many PC games, though performance varies depending on the title." The exploit leverages a patched hypervisor vulnerability to give Ubuntu unfettered control over the PS5's hardware, including its eight Zen 2 CPU cores and 16 threads.
Background
The ps5-linux-boot project is entirely unofficial and unsupported by Sony. Nguyen, a well-known figure in console security, previously worked on similar exploits for the PS4. The hack relies on a vulnerability in the hypervisor layer that Sony has already fixed in firmware 5.xx and later, limiting compatibility to older consoles.

"I've been sitting on this for months," Nguyen explained. "Now that the vulnerability is patched, there's no risk of Sony shipping a quick fix for new consoles, so I decided to release it publicly." Users must have a PS5 on firmware 3.xx or 4.xx, which excludes most consoles sold after early 2022.
What This Means
For the PS5 modding community, this opens the door to running a full desktop operating system on Sony's latest console. "This is a major step for homebrew on PS5," said Maria Chen, a security analyst who reviewed the project. "It shows the hardware is powerful enough to double as a PC, but the firmware restriction keeps it niche."
Gamers who own older PS5 units can now install Steam and access a library of tens of thousands of PC games. However, performance may not match a dedicated gaming PC due to the lack of GPU driver optimizations and limited memory bandwidth. "Don't expect to play the latest AAA titles at 4K," warned Nguyen. "But indie and older games run surprisingly well."
Risks and Limitations
- Bricking risk: Improper installation can render the console unusable. Users must carefully follow Nguyen's instructions.
- Warranty void: Running unofficial software violates Sony's terms of service and voids the warranty.
- No online play: The exploit disables PSN connectivity to avoid bans. Users play Steam games offline.
- Hardware damage: Overclocking or stress-testing Linux could damage the console's cooling system.
Community Reaction
The PS5 homebrew scene has erupted with excitement. "Finally, a reason to keep my old PS5 on 4.xx firmware," wrote one Reddit user. Others expressed caution, noting that Sony could legally target distributors of the exploit. "Nguyen is a legend, but this is definitely a gray area," said Chen.

Sony has not commented on the project. Historically, the company has taken a hard line against console modifications, issuing firmware updates to block exploits and pursuing legal action against modders. "I expect a firmware update to patch the vulnerability on older consoles soon," predicted gaming industry analyst James Wright. "But since the exploit only works on already-outdated firmware, many users will remain untouched."
Step-by-Step Guide to Boot Ubuntu on PS5
Nguyen has published detailed instructions on his GitHub repository. The process involves:
- Downloading the ps5-linux-boot payload and a compatible Ubuntu image.
- Preparing a USB flash drive with the boot files.
- Enabling a userland exploit via a web browser to load the payload.
- Inserting the USB and rebooting into Linux.
- Installing Steam and configuring graphics drivers.
"The whole thing takes about 30 minutes if you're familiar with Linux," Nguyen noted. "First-timers should budget a few hours." He emphasized that users must backup their PS5 data beforehand, as the exploit may corrupt the console's internal SSD.
Future Outlook
The release of ps5-linux-boot could spark a wave of similar projects for other consoles. "If Sony doesn't aggressively patch, we might see other researchers releasing exploits for newer firmware," said Wright. However, Nguyen cautioned that the vulnerability is deep in the hypervisor and unlikely to be rediscovered soon. "This is a one-time gift for the community," he said. "Enjoy it while it lasts."
For now, only a small fraction of PS5 owners can take advantage. But those who do will unlock a unique hybrid: a console that can play both PlayStation 5 games and Steam titles. "It's the best of both worlds," Chen concluded. "Just don't expect Sony to approve."
