CVE-2025-24223Network attack vector

Memory corruption via crafted web content

Published May 12, 2025 · Updated Apr 2, 2026

Memory corruption in WebKit across affected Apple products allows remote attackers to corrupt process memory via crafted web content. Apple identifies WebKit's memory handling as the locus but has not published the erroneous operation or memory object involved. Processing the crafted content is required; the documented consequence is process-memory corruption, with no published claim of code execution.
