A security researcher has found a new bug that will effectively crash and restart any iOS device. Sabri Haddouche tweeted about the bug that is basically just 15 lines of code. The bug is not only limited to iOS devices as it can also freeze Safari on Mac when opening the link. 

Haddouche posted the bug on GitHub along with the source code that is basically a few lines of HTML and CSS. The bug was tested even on Windows 7 machines where users reported the Safari app freezing and crashing. However, the bug did not crash iPhones when rising the link using Chrome or Firefox browsers.

Haddouche told TechCrunch “The code exploits a weakness in iOS' web rendering engine WebKit, which Apple mandates all apps and browsers use,” He explained that “nesting a ton of elements — such as "div" tags — inside a backdrop filter property in CSS, you can use up all of the device's resources and cause a kernel panic, which shuts down and restarts the operating system to prevent damage.”

“Anything that renders HTML on iOS is affected,” Haddouche told TechCrunch, which basically means that iPhones, iPads and the Safari browser can get affected when someone sends the link via email, social media and as a text message. 

9to5Mac goes further to explain that the bug basically overloads the WebKit renderer that leaves the system crippled. This, in turn, leads the system to reboot as it can only recover the kernel. 

Here's how the system reboot looks when one clicks on the bug link:

We sincerely advise you to click the link at your own risk as it will most definitely reboot your iPhone until Apple finds a fix.
