Even Apple released iOS 12.1.3 before S0rryMybad’s twitter announcement, he didn't mention that same exploit will work or not on iOS 12.1.3 version. Therefore, it can guess Apple has patched the bug which is found from S0rryMybad existing on iOS 12 to iOS 12.1.2 by releasing iOS 12.1.3.

Here is the screenshot of PoC bug on A12.
