Sony PS5 ROM key leaked: BootROM code may make hacking easier

A new report says a core ROM key for the Sony PS5 is now public. This key is part of the BootROM code that runs first when the console starts. The code checks if the boot file is real before the rest of the system can load. If the key is real and works as said, it could let skilled users read and study the boot path in full.

The key is burned inside the main chip and cannot be changed by any system update. That fact makes this case stand out from past bugs that were fixed with new code.
With the key in hand, a user may try to read the real boot file and learn how checks are done. This does not break the system on its own, but it gives a clear map of how the early boot stage works.

Why fixes are hard

The issue sits at a deep level in the chip. Since the key lives in read-only memory, Sony cannot block it with new system files. The only full fix would be a new chip made with a new key, which would only ship in a later model.
All PS5 units sold so far would still carry the old key. This does not mean every unit can now run fake code. Many other checks still guard the system. Each layer must be passed before any custom firmware can load.
Still, one major lock may now be weak. That lowers the work needed to test other paths. It may also help those who want to learn how the system runs, step by step, from power on to the home screen.

Past cases show risk

This is not the first time a game box faced a deep flaw. The PS3 had a design error in its encryption, which later let users run homebrew tools and copy games. The Switch also had a chip defect that could not be fixed by updates.
That flaw lets users boot Linux and other tools. In both cases, the first break did not lead to mass hacks at once. It took time, skill, and many tests. The same may happen here.
For now, this leak points to a long-term risk, not a sudden wave of cracked units. It does, however, mark a shift. A core confidential part may now be known, and that can shape what comes next for the PS5 scene.
