iOS 11.2.2 Jailbreak Tool Possible As Adam Donenfeld Discovered Kernel-Level Bug
Apple is indeed working hard to enhance its security, but then the hackers are doubling the effort to find vulnerabilities on iOS. In fact, Adam Donenfeld, a member of Zimperium zLabs was able to find another exploit, which might pave the way to iOS 11.2.2 jailbreak.
iOS 11.2.2 Possible Jailbreak
Donenfeld has confirmed that Apple has lastly acknowledged his “kernel heap overflow” bug through a series of tweets. In fact, the Cupertino–based company already fixed it as part of the iOS 11.2.5 release. Also, it was outlined as reference CVE-2018-4109 in Apple’s security release notes.
Moreover, the security researcher has also specified that he didn’t exactly write an exploit for this bug just to put it into practice. Instead, it is “accessible from the sandbox” and that present frameworks could put this to a good run through for the sake of an iOS 11.2.2 and lower jailbreak. Donenfeld tweeted the following:
“1/N Apple has finally acknowledged my kernel heap overflow and fixed it on 11.2.5 (CVE-2018-4109). While I didn’t write an exploit, it’s one of the most hidden vulnerabilities I’ve ever found, and it took me a couple of days to trigger it once I found it!”
“2/N Is there any session that would be interested in a detailed explanation + review of some tools I wrote to aid in that research?”
“3/N If it makes it better, in any case, this is accessible from the sandbox (so theoretically if someone plans to write an exploit, @Morpheus______’s jailbreak framework can be used with that)”
With the existence of this bug, it is safe to assume that the jailbreak enthusiasts could possibly see an iOS 11.2 – iOS 11.2.2 jailbreak in the future. As of this moment, the newest jailbreakable version of iOS is iOS 11.1.2, utilizing the tools like Electra or LiberiOS.
Additionally, it is also worth mentioning that this kernel heap overflow bug is already turned into an exploit. Hopefully, sooner or later, it will ultimately turn into a public jailbreak, by somebody who has the technical knowledge and capabilities.
Jailbreak Community Advancement
In the past few months, there have seen implausible progress in the jailbreak community. The majority of the said advancement was sparked by Ian Beer’s exploit resulting in a number of jailbreaking tools released.
In addition, it seems that the progress towards an iOS 11.2.2 jailbreak will be much faster. Nonetheless, perhaps due to a transformed energy in the jailbreaking community encouraged on by the initial jailbreaking of the iOS 11.1.x
It’s indeed significant to retell that if this kernel bug is turned into an exploit, jailbreak enthusiasts won’t see the same application for iOS 11.2.5 since Apple already addressed the issue. Luckily, those iOS devices owners with handsets running an older operating system, it’s likely that an iOS 11.2.2 jailbreak will arrive soon.
In contrary, to those who have upgraded their iOS device to 11.2.5, they’ll be going to be unlucky when it comes to jailbreaking their handset. But despite that, given the far-fetched progress in the jailbreak community, there’s still a possibility that an iOS 11.2.5 exploit will become available in the coming weeks.
As of now, these are the available information about the iOS 11.2.2 jailbreak tool progress. Stay tuned for more updates!
