CVE-2024-44126

Heap corruption via insufficient ARKit file checks

Published Oct 28, 2024 · Updated Apr 2, 2026

Heap corruption in Apple ARKit occurs when attackers supply a crafted file to affected iOS, iPadOS, macOS, or visionOS releases. ARKit processes the file with insufficient checks, but Apple has not disclosed the specific parser, field, or invalid memory operation. The file must be opened or processed locally; Apple reports heap corruption but does not claim code execution or a specific crash mode.
