PlayStation 4 News: TheFlow reports that a dongle jailbreak could not be made with a recent vulnerability found in FreeBSD due to Sony implementing their own HID descriptor – No updates on upcoming FW 6.20 hack
Any news regarding hacks on a PlayStation 4 firmware higher than 5.05 (or 5.07) is undoubtedly welcome but this time around, TheFlow has a bit of bad news on the subject as a chance for a potential jailbreak has been lost. In this article, we’ll be looking at what TheFlow’s news is about and how it may potentially affect future PS4 jailbreaks.
TheFlow finds a vulnerability which could’ve been used for a dongle-based PS4 jailbreak…. if Sony hadn’t used their own HID descriptor parser
For those out of the loop, TheFlow is a veteran in the PlayStation Vita scene having released software hacking solutions for FW 3.65-3.73 and in March, he stated that he was working on a hack for PlayStation 4 consoles running FW 6.20.
Yesterday, he tweeted out that he’d reported a vulnerability that affects OpenBSD and FreeBSD, upon which the PlayStation 4 firmware is based, having to do with malicious USB HID devices which could give out-of-bounds R/W access on the kernel heap.
Through this vulnerability, TheFlow stated that a dongle-based jailbreak could have been created for the PlayStation 4 and considering that it was only reported this week, all PlayStation 4 firmwares to date would have been vulnerable. However, this turned out NOT to be the case since Sony implemented their own HID (human interface device – these include peripherals like keyboards and mice) descriptor parser on the PlayStation 4 which is not vulnerable to bug that TheFlow found thus eliminating the possibility of a dongle-based jailbreak being released for the PS4 making use of it.
Does this affect the FW 6.20 jailbreak that TheFlow was working on?
As things stand, TheFlow has not divulged any information on whether the vulnerability he just reported affects his work regarding a Firmware 6.20 jailbreak despite some in the community thinking so. It is possible that the vulnerability was being considered as a potential entry point for hacking the PlayStation 4 but no information has been shared on this so for now, it is not possible to say whether this development affects the possibility of a FW 6.20 jailbreak.
However, the fact that TheFlow tested the vulnerability on the PlayStation 4 shows that he is still researching ways to exploit the console which means that eventually, we may see a hack for a firmware higher than FW 5.05 as TheFlow is known to have delivered in the past!
As usual, to follow the latest updates on what TheFlow is up to, it is advised to follow his Twitter profile linked below and till he confirms that a potential FW 6.20 jailbreak by him is out of the question, there is still hope!
