Apple has released a patch to iOS 12.4, with a fix to close the jailbreak Vulnerability . The vulnerability made it possible to jailbreak many recent iPhone models running iOS 12.4.
A jailbreak for iOS 12.4 was publicly released last week. The release came after it was discovered that Apple accidentally unpatched a vulnerability that was originally fixed in iOS 12.3. The bug in question was first reported to Apple by Google’s Project Zero team. Apple detailed the fix in the security release notes for iOS 12.4.
After hackers discovered that the vulnerability was once again available, it didn’t take long for a jailbreak to be created. The security issue also left iOS devices vulnerable to hacking attempts, which is why Apple likely worked quickly to correct it.
