At the same time, there is something that Apple can do about it. This says that since Checkm8 exploit is a hardware level exploit, it can’t be patched. Support for A10 and A10X devices is being worked on and is expected to be ready in the coming weeks. However, with the recently published blackbird vulnerability, we are able to get control of the Secure Enclave on A10 and A10X and disable this mitigation. Since checkm8 does not give us control over the Secure Enclave, this is not trivial to work around. In iOS 14, Apple added a new mitigation to SEPOS on A10 and above (except on Apple TVs and iBridge): if the device was booted from DFU mode and the Secure Enclave receives a request to decrypt user data, it will panic the device. The Checkra1n team explained this situation in the following blog post: But this endeavor requires more time and effort because it looks like Apple implemented a security mitigation to make Checkm8 exploit deployment more difficult on affected devices above A9(X). The plan of the Checkra1n team is to make jailbreak possible for newer devices on iOS 14 affected by Checkm8 Exploit. The restriction is that Checkra1n jailbreak supports only devices running on A9(X) processor or older. The bottom line of the statement is that Checkra1n version 0.11.0 supports iOS 14, however, with certain restrictions so far.
Apple released their iOS 14 and the Checkra1n team has already released their new Checkra1n app version supporting this latest version of the operating systems.
