Have you updated your iPhone yet?
Apple on Monday released iOS 16.3.1, an update to its operating system that fixes a vulnerability that hackers may have been actively exploiting in the wild.
According to Apple’s support page, the bug was in WebKit, the web browser engine used by Safari. The issue could allow an attacker to run code on someone else’s device.
iOS 16.3.1 also fixes a kernel issue at the core of the operating system that could allow an app to run 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, and also released security updates for macOS 13.2.1, iPadOS 16.3.1, and Safari 16.3.1.
