Published: 18 February 2026
Summary
CVE-2025-33252 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 40.7th 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-16 (Memory Protection).
Deeper analysis
CVE-2025-33252 is a vulnerability in the NVIDIA NeMo Framework that enables an attacker to cause remote code execution. A successful exploit could result in code execution, denial of service, information disclosure, and data tampering. The vulnerability is associated with CWE-502 (Deserialization of Untrusted Data) and has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). It was published on 2026-02-18.
The attack vector is local (AV:L), with low attack complexity and requiring low privileges (PR:L), no user interaction, and unchanged scope. A local attacker with low-level access to the affected system could exploit this flaw to achieve high impacts on confidentiality, integrity, and availability, potentially leading to the described outcomes including remote code execution.
Mitigation details are available in advisories from the National Vulnerability Database (https://nvd.nist.gov/vuln/detail/CVE-2025-33252), NVIDIA (https://nvidia.custhelp.com/app/answers/detail/a_id/5762), and CVE.org (https://www.cve.org/CVERecord?id=CVE-2025-33252).
