iOS 12 Jailbreak 2019 Update: Researcher Discovers New Vulnerability Built Upon Previously Existing Kernel Exploit
A significant chunk of Apple’s community is still waiting for a public iOS 12 jailbreak and so far none has been released. This isn’t surprising given that the Cupertino-based manufacturer has tightened its security measures with the A12 Bionic Chip.
But this doesn’t stop researchers from developing a fully functioning iOS 12 jailbreak. Their latest effort comes from Ian Beer of Google’s Project Zero who recently released a kernel exploit. Beer’s process is built upon a previous vulnerability developed by his colleague Brandon Azad. To put briefly, Azad created a bug that exploited the 12.1.3 version where it bypassed the security measure by making a “fake kernel task port,” VW reported.
This allowed the researchers to write a brand new kernel memory, although that exploit has since been addressed by the company. Now, Beer has managed to find a new a vulnerability based on Azad’s finding where it exploits the system through a “kernel heap overflow bug.” While Beer hasn’t fully created a working iOS 12 jailbreak that would benefit the community, he certainly is treading the right path.
So much so that his process could not only spell an iOS 12 jailbreak but would also translate to a macOS 10.14.2 version as well. However, those waiting for the full exploit shouldn’t hold their breath as it takes time to create such bypass for Apple devices.
Another promising avenue for an iOS 12 jailbreak that developers are currently tinkering at the moment is the OsirisJailbreak12, Business Times reported. Researcher Geo Snow posted his progress on Twitter along with a caveat for the optimists.
“Osiris Developer #Jailbreak for #iOS 12. No remount and no CoreTrust bypass yet. It gets root, escapes the sandbox and resprings. Feel free to build on top of it. Not for the general public!” Geo Snow posted. As of now, it’s still unclear how long the researchers can come up with a fully-functioning iOS 12 jailbreak that would wound its way to the public. But given that all these exploits can still be taken advantage, it’s still a reassuring thing to know that users can potentially distance their devices away from Apple’s tight grip.
