CVE-2024-23222Known exploitationPublic exploitNetwork attack vector

Code execution via stale DFG property value

Published Jan 23, 2024 · Updated Apr 2, 2026

Type confusion in WebKit on affected Apple platforms allows remote attackers to execute arbitrary code through malicious web content. JavaScriptCore's DFG compiler can freeze a stale property value after validating structure watchpoints without revalidating the value. A user must process attacker-controlled content; exploitation grants WebContent memory access and has been chained with later compromise stages.
