Apple has released security updates to macOS, iOS, and iPadOS to address a zero-day vulnerability in the WebKit browser engine that attackers may already have used in the wild.

The vulnerability tracked as CVE-2022-22620, a use after free issue that was addressed with improved memory management. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.

The WebKit is used in Safari, Mail, App Store, and many other apps on macOS, iOS, and Linux. WebKit can’t really be avoided; the best way to mitigate the risk posed by this vulnerability is to update.
