In today's video, we have pretty surprising news to discuss about the iOS 12.4.1 #Jailbreak status. A new kernel exploit with tfp0 which would basically jailbreak #iOS 12.4.1 fully has been achieved and will be released in the next couple of months by @ZecOps. This was pretty unexpected. As you probably know, iOS 12.4.1 has been released by Apple to patch the bug they should have patched back in iOS 12.3 (and they did, but they reintroduced it on 12.4 by mistake), so there are no major changes between iOS 12.4 and iOS 12.4.1 other than Ned Williamson's bug being patched, which means once this tfp0 exploit is released, Unc0ver can be updated for iOS 12.4.1 in literally one day.
The tfp0 term stands for task_for_pid(0), a function which when passed the argument 0 should not return the task port because 0 is the kernel and one can't have kernel task port, but since the exploit runs, the kernel task port is obtained and so Kernel Memory Read / Write can be done arbitrarily thus enabling a jailbreak to be applied. So a tfp0 kernel exploit is 99% of what you need for a jailbreak.
