Published: 09 December 2025
Summary
CVE-2025-33214 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Custhelp (inferred from references). Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 28.8th 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).
Deeper analysis
CVE-2025-33214 affects NVIDIA NVTabular for Linux in its Workflow component, where a deserialization issue (CWE-502) can be triggered by a user. This vulnerability, published on 2025-12-09T18:15:49.610, carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low complexity, and significant impacts on confidentiality, integrity, and availability.
Attackers require no privileges (PR:N) but need to lure a user into some interaction (UI:R), such as processing malicious input over the network (AV:N). Successful exploitation could enable arbitrary code execution, denial of service, information disclosure, or data tampering on the targeted system.
