Russ Cox of Google has been credited with finding and reporting a kernel level bug to Apple, which has since been patched with yesterday’s release of iOS 11.3.

Now, according to Cox himself, he has full intentions to release the kernel bug into the public domain, which could lead to the creation of an iOS 11.2.5 jailbreak if exploited.
As you may already know, Apple recently released iOS 11.3 to the general public, which was inclusive of a number of fixes and improvements, such as bringing HomePod support in anticipation of next month’s release, and additional power for Siri in the form of being able to offer news broadcasts.
