Hackers have launched a brand new PS4 jailbreak for firmware model 9.00. Titled “pOOBs4”, the jailbreak takes benefit of a filesystem bug within the 9.00 firmware replace. Notably, the kernel exploit used to make this jailbreak additionally impacts PS5 consoles, which means we could also be getting a jailbreak for the PS5 within the close to future.
The jailbreak works via utilizing an present WebKit exploit, which hacker TheFlow0 discovered earlier this yr. Exploiting WebKit — the engine that common internet browsers similar to Google Chrome and Safari are primarily based on — permits hackers to execute code beneath the guise of a daily utility.
Nevertheless, that is solely step one in jailbreaking a PS4 console. The second step requires hackers to discover a vulnerability within the console’s kernel — the core of the console’s working system. Doing so would open up the doorways to homebrewing and different kernel-level modifications. Beforehand, hackers had solely discovered kernel vulnerabilities up till firmware 7.55. In case you needed to jailbreak a PS4 with a firmware model later than that, nonetheless, you have been out of luck. That’s, in fact, till now.
Alright, was only a joke about caturday.
The exploit is legit, and as a bonus:
The kernel exploit impacts Playstation5 as nicely!
(no, ps5 will not be prepared or being launched, the lead developer doesn’t at the moment have a ps5 console)

Earlier in November, hacking group fail0verflow made a breakthrough after discovering the console’s root keys. This permits hackers to start the seek for firmware vulnerabilities. What precisely this implies for the way forward for PS5 homebrewing is unclear. Whereas the lead developer of the brand new PS4 9.00 jailbreak at the moment doesn’t have entry to a PS5 with a purpose to check kernel vulnerabilities, it looks like it’s solely a matter of time earlier than they discover one.
