CVE-2025-43234

App crash via malformed Metal texture

Published Jul 29, 2025 · Updated Apr 2, 2026

Memory corruption in Metal across affected Apple systems allows attackers to terminate an app by processing a maliciously crafted texture. Metal inadequately validates untrusted texture data during processing, allowing multiple memory-corruption conditions to trigger unexpected termination. Apple has not disclosed the specific malformed fields, delivery path, or required privileges, so the demonstrated consequence is limited to an application crash.
