CVE-2024-54497Network attack vector

Denial of service via crafted web content

Published Jan 27, 2025 · Updated Apr 2, 2026

Denial of service in QuartzCore across Apple operating systems allows remote attackers to interrupt affected processes via crafted web content. Apple identifies improved checks as the correction but has not published the QuartzCore routine, input field, or erroneous operation responsible. Exploitation requires an affected device to process attacker-controlled web content; the documented consequence is availability loss, with no reported data access, code execution, or system reboot.
