## Technical details

This vulnerability is classified as an improper validation of array index (CWE-129) within the JavaScriptCore component of Apple's operating systems and Safari browser. The root cause is a lack of sufficient bounds checking when processing web content. An attacker can exploit this by hosting a specially crafted website; when a user visits the site, the engine fails to validate array boundaries, leading to arbitrary code execution. This flaw has been added to the CISA Known Exploited Vulnerabilities (KEV) catalog, indicating active use by threat actors. Patches are available in macOS Monterey 12.5, iOS/iPadOS 15.6, tvOS 15.6, watchOS 8.7, and Safari 15.6.
