Perhaps you remember how in late January, Rani Idan of Zimperium zLabs announced that he had discovered several
Apple fixed vulnerabilities in iOS 11.2.5 and higher, and Idan published another post about creating an exploit based on vulnerabilities and publishing it publicly.
This is great news, because based onexploit it is possible to create a jailbreak for iOS 11.2.2. Idan posted another post on Zimperium's official website called “CVE-2018-4087 PoC: Escaping the sandbox by misleading bluetoothd”, the first part of which consists of a bug code, which Apple described in a security update post.
He writes that the exploit is published for research purposes and should not be used with bad intentions.
Both vulnerabilities discovered were fixed by Apple.in iOS 11.2.5, tvOS 11.2.5 and watchOS 4.2.2, which means they do not concern the latest firmware versions. However, users with iOS 11.2.2 can still get a new jailbreak if someone undertakes to create it.
The same thing happened with the exploit of Ian Beer "aysnc_wake", which led to the creation of several jailbreak tools at once, including Electra.
There is no guarantee that vulnerabilities will lead tojailbreak for iOS 11.2.2, but hope not to lose. The Zimperium zLabs team did a good job of discovering vulnerabilities, describing them and publishing them publicly. Now it's up to the tool developers.
Recall again that the vulnerabilities have been fixedon iOS 11.2.5 and iOS 11.2.6. If you have not upgraded to these versions, then it is not necessary. Perhaps, jailbreak will be released soon for your firmware. It remains only to wait and follow the news.
