The PlayStation 5’s ROM keys have allegedly been leaked, meaning anyone who can get their hands on the hex strings now has the hardware code that will allow jailbreakers to try decrypting and analyzing the console’s bootloader. According to The Cybersec Guru, this is an unpatchable problem for Sony, because these keys cannot be changed and are burned directly in the APU. The only way that the company can invalidate the leaked codes is to replace the chips on yet-to-be-manufactured units, meaning consoles that are already in the wild could possibly take advantage of future jailbreaks stemming from the use of these leaked codes.
When you turn on the PS5, its CPU runs the BootROM code that’s baked in the chip and uses the ROM keys to ensure that Bootloader is valid. Now that the ROM keys have been leaked (and assuming they are valid), a hacker could then decrypt and study the official bootloader and potentially use that as a starting point to understand how the PS5’s boot system works. Since the issue is at a hardware level, Sony would not be able to release an update that will stop consoles with the compromised chip from loading kernel-level exploits in the future, should one become available.
