Apple rolls out iOS 18.1.1 with critical security patch to iPhones

Apple has released iOS 18.1.1 to all iPhones worldwide. Recently, it came to light that a zero-day vulnerability in JavaScriptCore and WebKit of iOS devices was actively exploited by threat actors.

For the uninitiated, zero-day means a software security vulnerability that the concerned experts (in this case, Apple engineers) were previously unaware of but which may have been exploited by some hackers to attack systems.

The latest update, which is 400MB in size, fixes these vulnerabilities.

Apple has thanked Clément Lecigne and Benoît Sevens of Google's Threat Analysis Group for the early detection of the threat and help resolving the issue.

Apple has rolled out a similar update (iPadOS 18.1.1) for iPads. Device owners are advised to upgrade to the latest version at the earliest to safeguard against cyber threats.
