CVE-2025-43253

Arbitrary binary launch via improper input validation

Published Jul 29, 2025 · Updated Apr 2, 2026

Improper input validation in Apple macOS before 14.7.7 or 15.6 allows attackers to launch arbitrary binaries through a malicious app. The affected AppleMobileFileIntegrity component accepts insufficiently validated input, but Apple has not disclosed the input, operation, or binary-selection path. Exploitation requires a malicious app already running on the Mac and can start an attacker-chosen binary on that trusted device.
