A spark of good news seems to be circulating in the jailbreak community this week after an iOS 11.2.x-based kernel exploit became publicized.
And if that news wasn’t good enough in and of itself, a Tweet shared by renowned iOS developer and Electra jailbreak tool creator CoolStar underscores interest in toying around with it:
iOS 11.2.x PoC looks very interesting, will be taking a look at 11.2 - 11.2.6 when I get the time....

The Tweet isn’t a guarantee that CoolStar will implement an iOS 11.2.x jailbreak based on the new exploit, but rather a word of enlightenment that it could be possible. At this point in time, it’s too early to tell what could materialize after everything is said and done.
Given the current circumstances, we’d recommend that any avid jailbreakers using iOS 11.2-11.2.6 stay put and avoid upgrading their firmware. It seems that CoolStar agrees with this logic:
iOS 11.3 and later don’t appear to be vulnerable to the exploit mentioned above, so upgrading would be counterproductive should you possess an ounce of interest in jailbreaking iOS 11.2.x.
As of this writing, Saurik has yet to update Cydia or Mobile Substrate with official support for iOS 11, but CoolStar’s Electra jailbreak for iOS 11.0-11.1.2 bundles a modified version of Cydiaand a Substrate substitute that appear to work just as well. Any future jailbreak from CoolStar, should it surface, would likely bundle similar utilities.
