CVE-2023-41983Network attack vector

Application crashes via WebKit memory mishandling

Published Oct 25, 2023 · Updated Feb 13, 2025

Denial of service in WebKit Process Model affects Apple iOS, iPadOS, Safari, and macOS and allows remote attackers to crash apps. The process model mishandles memory while processing untrusted web content; Apple has not disclosed the faulty function or operation. Exploitation requires a user to load attacker-controlled content, and the documented consequence is application termination rather than data access or code execution.
