CVE-2025-30440

Local ASLR bypass

Published May 12, 2025 · Updated Jul 25, 2026

Incorrect authorization in Libinfo in Apple macOS before 13.7.6, 14.7.6, or 15.5 allows local users to bypass ASLR through an app. Apple has not published which Libinfo check accepts or returns untrusted state incorrectly. Execution requires a local app and user interaction; the bypass weakens address randomization but does not alone grant code execution.
