New POC kernel bug may be helpful to achieve unc0ver iOS v13.3.1 Jailbreak. In recent months unc0ver team has released unc0ver Jailbreak for the devices running iOS 13.0 to iOS13.3, but leaving behind iOS 13.3.1 support. The lowest available update that Apple wants to register at the time of this writing is iOS 13.3.1, but unc0ver doesn’t support this build of iOS yet.
Thankfully, Twitter user @_simo36 has posted a valuable new POC kernel bug proof of the concept that supports iOS 13.3.1, and even though it needs to be verified that this bug will achieve tfp0, it is apparently accessible from the sandbox.
Security expert and leading hacker Pwn20wnd retweeted this post; giving value to the unc0ver project team is actually looking in to the potential of exploiting this exploit. This being said, it does not promise its feasibility, and at best the decision to downgrade is pure caution.
Benjamin Weaver, a prolific internal software tester for unc0ver, recently tweeted that enthusiastic jailbreakers must not update iOS 13.4, or that any who do should revert to iOS 13.3.1 instantly unless Apple removes the signing window If the case might be, and whether or not this Kernel Bug creates a jailbreak on all users using iOS 13.3.1, it is still best to uninstall all scratching from iOS 13.4 to get jailbreak. Once a jailbreak is released, older iOS versions are more likely to be supported; iOS 13.3.1 will have a much higher probability of getting jailbreak than iOS 13.4.
