CVE-2026-65179: CWE-502 Deserialization of Untrusted Data in NVIDIA NeMo Speech
NVIDIA NeMo contains a vulnerability in the TabularTokenizer class where it deserializes an untrusted, attacker-controlled .pkl file via pickle.load() without validation. A successful exploit of this vulnerability may lead to code execution, data tampering, denial of service, and information disclosure.
AI Analysis
Technical Summary
The vulnerability exists in the TabularTokenizer component of NVIDIA NeMo Speech, where it deserializes attacker-controlled pickle (.pkl) files without proper validation. This unsafe deserialization (CWE-502) allows an attacker to execute arbitrary code, manipulate data, cause denial of service, or disclose sensitive information. The CVSS 3.1 base score is 8.8, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can result in remote code execution, unauthorized data modification, denial of service conditions, and leakage of sensitive information within the affected NVIDIA NeMo Speech environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid loading untrusted .pkl files with the TabularTokenizer class to prevent exploitation.
