Apple has released a new iOS 11.2.6 update that includes a fix for the bug that is causing iPhones and apps like Facebook and WhatsApp to crash when a Telugu single character is received via iMessage.

The bug was discovered last week and involves sending the character in Telugu to devices that crashes an iPhone and makes apps like Messages, Facebook Messenger and WhatsApp inaccessible.

The bug also affects Safari and the built-in Messages app on macOS and the Apple Watch.

"Apple released updates for watchOS, tvOS, and macOS to stop the crash from happening on those platforms, too," The Verge reported on Tuesday.

When the Telugu character is sent in an iMessage, it can freeze up the entire Messages app on all of a person's Mac and iOS devices.

The Messages app will then refuse to function properly until the offending character is removed by deleting the conversation with the person who sent it.

In some situations, if the character is viewed through an iOS notification, it can cause the entire device to crash.

The Cupertino-based company had earlier said it was working to fix the vulnerability that affects iPhones, iPads, Macs, Apple Watch and Apple TV running the latest versions of their operating software.

Apple announced last month that the upcoming Apple iOS 11.3 update will offer features that gives users power to control their batteries, Augmented Reality (AR) upgrade and Animoji.

"While iOS 11.3 fixes the problems, Apple said it is planning to release an iOS 11 update soon that will address the crashes before the iOS 11.3 release in the spring," The Verge had reported earlier. 

"This spring, iOS 11.3 will deliver exciting new ways to experience Augmented Reality on iPhone and iPad, new Animoji on iPhone X and the ability to view health records in the Health app," Apple had said earlier.
