Exploitation Conditions

Exploitation requires (1) the target Triton Inference Server deployment must have the DALI backend enabled and loaded, (2) the attacker must hold low-privilege authenticated access to submit inference requests or model/pipeline configurations to the Triton API (PR:L), and (3) user interaction is required (UI:R), implying an operator or another user must trigger loading or execution of the attacker-supplied DALI pipeline. Exploitation is limited by these factors: deployments not using the DALI backend are not exploitable, anonymous unauthenticated network attackers cannot directly exploit the flaw, and the UI:R requirement excludes fully automated drive-by exploitation against headless services.

Impact

CVSS 8.0 (High) reflects network-reachable exploitation (AV:N) with low complexity (AC:L) but requires low privileges (PR:L) and user interaction (UI:R), with high impact across confidentiality, integrity, and availability. EPSS score is not provided in the input data. The CVE is not listed in CISA KEV and no public exploit code has been identified, indicating no confirmed active exploitation. The PR:L + UI:R combination materially limits real-world attack surface - exploitation likely requires an authenticated model-deployment user submitting or triggering a malicious DALI pipeline, not anonymous internet exploitation. Real-world risk is highest in multi-tenant ML serving environments where untrusted users can submit models or preprocessing configurations; in single-tenant internal deployments the practical risk is lower despite the High CVSS.

Exploit ScenarioDerived

An authenticated user with permission to submit inference requests or model configurations crafts a malicious payload - for example, a manipulated tensor shape, batch size, or preprocessing parameter - that triggers integer overflow inside the DALI backend's allocation or indexing logic. After luring an operator into loading or executing the malicious model/pipeline (satisfying the UI:R requirement), the resulting memory corruption can be steered toward arbitrary code execution under the Triton server process, tampering with served model outputs, or crashing the inference service. No public exploit code has been identified at time of analysis.

AnalysisAIv1 – May 20, 2026

Integer overflow in the DALI backend of NVIDIA Triton Inference Server allows authenticated remote attackers to trigger memory corruption that may result in code execution, data tampering, or denial of service. The flaw requires low-level privileges plus user interaction (CVSS 8.0, AV:N/AC:L/PR:L/UI:R) and affects deployments exposing the DALI inference pipeline. No public exploit identified at time of analysis.

RemediationAI

Patch available per vendor advisory at https://nvidia.custhelp.com/app/answers/detail/a_id/5828 - administrators should consult NVIDIA's security bulletin for the exact fixed Triton Inference Server release and upgrade accordingly. Until patched, compensating controls include disabling the DALI backend in Triton's model configuration if not required (trade-off: loss of GPU-accelerated preprocessing performance), restricting model upload and inference-request access to trusted authenticated users only via network segmentation and authentication proxies (trade-off: reduced accessibility for legitimate ML practitioners), and reviewing DALI pipeline definitions for untrusted user input.

Technical ContextAI · show details

Triton Inference Server is NVIDIA's open-source platform for serving AI/ML models across frameworks (TensorFlow, PyTorch, ONNX, TensorRT). The DALI (Data Loading Library) backend accelerates data preprocessing pipelines on GPUs for inference workloads. The root cause is CWE-190 (Integer Overflow or Wraparound) - arithmetic operations on attacker-influenced size or count values wrap past integer bounds, producing undersized allocations or out-of-bounds memory accesses during DALI's data handling. The affected CPE is cpe:2.3:a:nvidia:triton_inference_server with versions unspecified, indicating the version range is to be defined by the vendor advisory.

DescriptionNVD

NVIDIA Triton Inference Server contains a vulnerability in the DALI backend where an attacker could cause an integer overflow. A successful exploit of this vulnerability might lead to code execution, data tampering, or denial of service.

Executive ViewAI

Why It Matters

NVIDIA Triton Inference Server's DALI backend contains an integer overflow vulnerability allowing authenticated attackers to achieve code execution or denial of service against inference workloads. Organizations running DALI-based inference pipelines risk compromise of model integrity, data manipulation, or service disruption. This affects deployments where inference servers are accessible to authenticated users or where user interaction with untrusted inputs is possible.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: (1) Network segmentation-restrict inference server access to trusted internal networks only; (2) Access controls-enforce strong authentication and limit users with inference pipeline interaction rights; (3) Monitoring-implement alerting on memory errors, process crashes, and inference pipeline anomalies; (4) Input validation-restrict inference requests to known-safe model inputs where feasible.

Attack Technique

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
