Summary

CVE-2025-33238 is a high-severity Race Condition (CWE-362) vulnerability in Nvidia Triton Inference Server. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as NLP and Transformers; in the LLM/Generative AI Risks risk domain.

The strongest mitigations our analysis identified map to SC-39 (Process Isolation) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

CVE-2025-33238 is a vulnerability in the Sagemaker HTTP server component of NVIDIA Triton Inference Server, where an attacker can trigger an exception. Published on 2026-03-24, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity primarily due to its impact on availability. The issue is associated with CWE-362 (race condition) and lacks additional CWE details from NVD.

A remote, unauthenticated attacker can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation leads to a denial of service condition by causing an exception that disrupts server availability, without compromising confidentiality or integrity.

Mitigation guidance and patch details are available in the official advisories, including the NVIDIA security bulletin at https://nvidia.custhelp.com/app/answers/detail/a_id/5790, the NVD entry at https://nvd.nist.gov/vuln/detail/CVE-2025-33238, and the CVE record at https://www.cve.org/CVERecord?id=CVE-2025-33238.

Mitigating Controls (NIST 800-53 r5) AI

Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.

Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

finds

Security testing can detect race conditions, but does not prevent them at design or coding time.

prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

none

Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
