Have you updated your iPhone yet?
Apple has released iOS 16.3.1, an update to its operating system that fixes a security vulnerability that hackers may have exploited in the wild.
According to Apple's support page, the bug was in WebKit, the web browser engine used by Safari. The problem could allow an attacker to execute code on someone's device.
iOS 16.3.1 also fixes an issue in the Kernel at the core of the operating system that could allow an app to execute arbitrary code with kernel privileges.
The update comes just weeks after the release of iOS 16.3, which added the ability to use security keys for two-factor authentication.
Apple said the issues affect iPhone 8 models and later. It also released macOS 13.2.1, iPadOS 16.3.1 and Safari 16.3.1 security updates.
