What is CVE-2025-62608?

The MLX framework, designed for machine learning on Apple silicon, is susceptible to a heap buffer overflow that occurs in the mlx::core::load() function when processing specially crafted NumPy .npy files. This vulnerability allows an attacker to manipulate the input file, resulting in a 13-byte out-of-bounds read. Exploiting this issue may cause the application to crash or potentially leak sensitive information. Users are strongly advised to upgrade to version 0.29.4 or later, where this security flaw has been addressed.
