Andy Nguyen leaves the PS5 scene and halts Linux development for the PS5 Pro after reporting a hypervisor bug to Sony.

# TheFlow Quits PS5 Linux Development, Putting PS5 Pro Support on Hold **PlayStation security researcher Andy Nguyen, better known as TheFlow, has announced that he is stepping away from the PS5 scene and ending his work on PS5 Linux, including planned support for PS5 Pro.** Nguyen [confirmed his departure](https://x.com/theflow0/status/2099987019954831744) after months of work on the project, saying he had originally planned to finish PS5 Pro compatibility and publish it in 2027. That release is now unlikely to happen through Nguyen himself. His decision does not appear to stem from a major technical obstacle. Instead, TheFlow has pointed to frustration with the direction of the PS5 hacking community, particularly the growing use of large language models to discover vulnerabilities and generate exploit code. A dispute involving a PS5 hypervisor vulnerability also appears to have played a major role in his decision. ## TheFlow had been working on PS5 Pro Linux support Nguyen says he spent several months developing the PS5 Linux project and had already started preparing support for Sony’s newer PS5 Pro hardware. The plan was reportedly to finish the work and make it public in 2027. That development has now stopped, leaving PS5 Pro without an official path to Linux support through TheFlow’s project. The current public codebase still focuses on the original PS5 and PS5 Slim, while the PS5 Pro work appears to have remained private. This distinction is important because other developers can continue working on the existing open-source project, but they cannot simply pick up Nguyen’s unfinished PS5 Pro implementation if the relevant code was never published. ## AI-assisted exploit development became a point of frustration One of the main issues raised by Nguyen concerns the increasing use of AI tools in security research. He argues that parts of the console hacking scene are becoming more dependent on large language models for finding bugs and producing exploit code. According to his comments, this can result in developers creating working exploits without necessarily understanding all of the low-level mechanisms involved. That criticism represents Nguyen’s own view of the current PS5 research community and should not be interpreted as applying to every developer involved in console modding. Still, his comments reflect a broader change taking place across software security, where AI tools are increasingly being used for reverse engineering, source-code analysis and vulnerability discovery. ## A PS5 hypervisor vulnerability appears to have triggered the decision The immediate trigger behind Nguyen’s departure appears to involve a previously unknown PS5 hypervisor vulnerability. Nguyen says he had already discovered the flaw and intended to keep it private for future research. Another researcher later reported the vulnerability to Sony after a third party apparently identified the same issue using AI-assisted tools. For Nguyen, that effectively removed one of the remaining valuable vulnerabilities available for his research. He claims that the bug was the final usable hypervisor vulnerability within the environment he had been working with. ## Why PS5 hypervisor exploits are so valuable The hypervisor sits at a highly privileged level within the PlayStation 5 security architecture. Breaking through that layer can potentially provide significantly more control over the system than exploits limited to the browser or even parts of the operating-system kernel. That level of access is particularly valuable for projects such as Linux, hardware research and advanced homebrew development. Nguyen had reportedly chosen not to disclose the vulnerability immediately because keeping it private would allow it to remain useful for future PS5 development. He also says that he asked other researchers to delay reporting the flaw until after the release of **Grand Theft Auto VI**. The idea was that users with vulnerable consoles could potentially purchase and play the game legally while still keeping firmware versions suitable for Linux and homebrew research. According to Nguyen, the researchers initially agreed to wait, but the vulnerability was ultimately reported to Sony soon afterward. ## Vulnerable PS5 consoles may still remain exploitable Sony being informed about the vulnerability does not automatically disable it on every PS5. The company would generally need to patch the issue through a system software update. Consoles that remain on older, vulnerable firmware versions could therefore potentially continue using the exploit if researchers eventually release working code for it. This is already common within console hacking communities, where users interested in homebrew often avoid firmware updates in order to preserve known vulnerabilities. ## Linux already runs on PS5 and PS5 Slim TheFlow’s departure does not affect the Linux code that has already been released. The public **ps5-linux-loader** project remains available and supports selected versions of the original PS5 and PS5 Slim. Depending on the console and exploit used, compatibility currently covers firmware versions ranging approximately from **3.00 to 7.61**. Earlier work has already demonstrated that full Linux distributions can boot on compatible PS5 systems. Ubuntu has also been [successfully demonstrated running on PS5 hardware](https://fanaticosdelhardware.com/ps5-ejecuta-ubuntu-26-04-con-kernel-linux-7-0-tras-publicarse-el-metodo-completo-de-jailbreak/). The Linux environment can access a surprisingly large amount of PS5 hardware. Existing implementations support features including HDMI output at up to 4K60, M.2 SSD storage, Ethernet, internal Bluetooth and Blu-ray hardware. Developers have also made progress with AMD GPU support through Linux graphics drivers. ## PS5 Linux can access the console’s full CPU One of the most significant achievements of the project is access to the PS5’s CPU configuration. Linux can use all **8 cores and 16 threads** of the console’s Zen 2 processor. Available tools also allow CPU frequencies of up to around 3.5 GHz, while the GPU can operate at frequencies close to 2.23 GHz under supported configurations. The system still has limitations and cannot be treated exactly like a traditional PC. Some hardware components remain partially supported or require workarounds, and the overall Linux experience depends heavily on the console firmware and exploit chain being used. Even so, the project has progressed far enough for users to run applications such as **Steam and multiple emulators**. That makes PS5 Linux one of the most technically significant developments in the PlayStation 5 homebrew scene so far. ## Open-source development can continue without TheFlow The future of the project is not entirely dependent on Nguyen. The **ps5-linux-loader** repository is distributed under the GPL-3.0 licence, allowing other developers to study, modify and fork the existing code. That means support for the original PS5 and PS5 Slim can continue evolving even without TheFlow’s direct involvement. PS5 Pro presents a much bigger challenge. Nguyen’s unfinished PS5 Pro work does not currently appear in the public repository, meaning future developers may need to independently reproduce much of the research required to support the newer console. The loss is therefore much more significant for PS5 Pro than for older models. ## PS5 Pro Linux now has an uncertain future TheFlow’s exit does not prove that Linux will never run on PS5 Pro. Other researchers could eventually develop their own implementation, and previously vulnerable firmware may continue to offer opportunities even after Sony patches newer system versions. However, losing several months of unpublished work from one of the most experienced PlayStation security researchers creates a substantial setback. For now, **PS5 Linux remains alive on original and Slim consoles, while PS5 Pro support has effectively been left without a roadmap**. The existing open-source code can still be developed by the community, but replacing Nguyen’s private PS5 Pro research may require significant additional reverse engineering. His departure also illustrates how rapidly AI tools are changing vulnerability research. LLMs can make exploit development and code analysis more accessible, but TheFlow’s criticism highlights an ongoing debate over the difference between generating working exploit code and fully understanding the systems being attacked. For the PS5 scene, however, the immediate consequence is much simpler: one of its most prominent researchers has stepped away, and PS5 Pro Linux development has lost its expected 2027 release path.
