CVE-2023-42981Network attack vector

Crash or memory disclosure via unchecked file processing

Published Apr 11, 2025 · Updated Apr 11, 2025

Improper input validation in Model I/O in Apple macOS before 14 allows remote authenticated users to crash processing or disclose memory. Apple states only that Model I/O performs inadequate checks while processing the file; no public source identifies the specific parser, field, or faulty operation. Exploitation requires low-privileged access and attacker-controlled file data, and the reported consequences are limited to denial of service or memory disclosure.
