CVE-2025-33244 is a critical vulnerability in NVIDIA APEX for Linux, a PyTorch extension commonly used for mixed-precision and distributed AI training. The issue is a deserialization of untrusted data flaw affecting environments that use PyTorch versions earlier than 2.6. NVIDIA states that an unauthorized attacker could trigger unsafe deserialization in the affected environment. Specific vulnerable functions or code paths are not provided in the available content, but successful exploitation could result in arbitrary code execution as well as broader compromise of the AI training environment.
