Apple on Monday rolled out security updates for iOS, iPadOS, macOS, and Safari to address a zero-day flaw that it said has been actively exploited in the wild.
Tracked as CVE-2023-23529, the issue relates to a type confusion bug in the WebKit browser engine that could be activated when processing maliciously crafted web content, culminating in arbitrary code execution.
The iPhone maker said the bug was addressed with improved checks, adding it's "aware of a report that this issue may have been actively exploited." An anonymous researcher has been credited with reporting the flaw.
It's not immediately clear as to how the vulnerability is being exploited in real-world attacks, but it's the second actively abused type confusion flaw in WebKit to be patched by Apple after CVE-2022-42856 in as many months, which was closed in December 2022.
