CVE-2025-31235

Local system termination via Audio double free

Published May 12, 2025 · Updated Apr 2, 2026

Double free in the Audio component of macOS and iPadOS allows local users to cause unexpected system termination through an app. The component releases the same memory allocation twice, but Apple has not disclosed the affected function or app-controlled operation that triggers the second release. The app must execute locally; the documented consequence is system termination, with no reported data disclosure or modification.
