CVE-2025-33241 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Nvidia Nemo. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 40.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates CVE-2025-33241 by requiring identification, testing, and installation of patches for the deserialization vulnerability in NVIDIA NeMo Framework.
Prevents exploitation of the deserialization of untrusted data vulnerability by validating and sanitizing maliciously crafted files before loading in the framework.
Limits the impact of privilege escalation and code execution from low-privilege local attackers by enforcing least privilege on users and processes.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Deserialization of untrusted data (CWE-502) in a framework enables local exploitation for client-side code execution (T1203) and subsequent privilege escalation (T1068) via a crafted file.
NVD Description
NVIDIA NeMo Framework contains a vulnerability where an attacker could cause remote code execution by loading a maliciously crafted file. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.
Deeper analysisAI
CVE-2025-33241 is a vulnerability in the NVIDIA NeMo Framework that enables an attacker to cause remote code execution by loading a maliciously crafted file. Published on 2026-02-18T14:16:02.927, it carries a CVSS v3.1 base score of 7.8 (High), with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, and is linked to CWE-502 (Deserialization of Untrusted Data). Successful exploitation might result in code execution, escalation of privileges, information disclosure, and data tampering.
The vulnerability can be exploited by a local attacker who has low privileges and requires only low-complexity actions with no user interaction. Upon successful exploitation, the attacker can achieve high impacts to confidentiality, integrity, and availability, potentially leading to the described outcomes of code execution, privilege escalation, information disclosure, and data tampering within the affected system's scope.
