CVE-2022-32886Network attack vector

Remote code execution via WebKit buffer overflow

Published Sep 20, 2022 · Updated May 29, 2025

Arbitrary code execution in Apple WebKit before Safari 16, iOS 16, or iPadOS 15.7 allows remote attackers to compromise devices via malicious web content. WebKit mishandles bounds during processing of crafted content, causing a buffer overflow that can be driven when a victim loads the content. Exploitation requires user interaction with the attacker-controlled website; the published impact includes code execution with confidentiality, integrity, and availability consequences.
