| Exploitation Conditions | No special conditions - remote unauthenticated exploitation against default configurations of NVIDIA Triton Inference Server, as indicated by the CVSS vector AV:N/AC:L/PR:N/UI:N requiring only network reachability to the Triton inference endpoints (HTTP/REST or gRPC). The primary limiting factor is network exposure: Triton is most often deployed inside trusted MLOps clusters behind ingress controllers or service meshes, so internet-exposed instances are the highest-risk population, while internal-only deployments require an attacker with east-west network access. The vulnerable Triton version range is not narrowed in the provided CPE, so confirmation against the NVIDIA advisory is required to determine whether a given deployment is actually in scope. |
| Impact | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H gives a strong network-reachable, unauthenticated, low-complexity profile with availability-only impact, scoring 7.5 (High). No EPSS score, KEV listing, or public POC was provided in the source data, so real-world exploitation pressure currently appears low and this is not confirmed actively exploited (CISA KEV). However, Triton instances are increasingly exposed to internal and sometimes external networks in MLOps pipelines, and a single crafted request that crashes the inference service would directly impact dependent applications - making this a meaningful priority for any team running Triton in production despite the absence of exploitation signals. Note that key data is missing: EPSS, KEV, and POC availability are not present in the input, and the CPE version range is unbounded, so defenders should treat the vulnerable-version scope as unconfirmed until verified against the NVIDIA advisory. |
| Exploit ScenarioDerived | An attacker with network reachability to a Triton Inference Server endpoint sends a crafted inference or management request containing values designed to trigger the integer overflow during request parsing or tensor size computation. The wrapped integer drives the server into a crash or unrecoverable state, taking the inference service offline and disrupting any application that depends on the served models. No public exploit has been identified at time of analysis, but the AV:N/AC:L/PR:N/UI:N profile makes opportunistic scripted exploitation straightforward once details emerge. |

Alert meAnalysisAIv1 – May 20, 2026
Denial of service in NVIDIA Triton Inference Server can be triggered remotely by unauthenticated attackers via an integer overflow condition (CWE-190). The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis. Defenders running Triton in network-exposed inference deployments should prioritize patching since exploitation requires no privileges, no user interaction, and low attack complexity.
RemediationAI
Patch available per vendor advisory - consult the NVIDIA security bulletin at https://nvidia.custhelp.com/app/answers/detail/a_id/5828 for the exact fixed Triton Inference Server version and upgrade accordingly; exact fix version was not provided in the input data and should not be inferred. Until patched, restrict network exposure of the Triton HTTP and gRPC inference endpoints (default ports 8000, 8001, 8002) to trusted clients only via firewall rules, service mesh policies, or Kubernetes NetworkPolicies, accepting that this breaks any cross-tenant or external inference consumers. Place an authenticating reverse proxy or API gateway in front of Triton to drop anomalous or oversized inference requests, and monitor the server for unexpected restarts that may indicate exploitation attempts; rate-limit inbound inference requests to slow brute-force crash attempts, with the trade-off of throttling legitimate high-volume workloads.

Technical ContextAI · show details
NVIDIA Triton Inference Server is an open-source serving platform used to deploy and scale AI/ML models (TensorRT, PyTorch, ONNX, TensorFlow, Python backends) across GPU and CPU infrastructure, typically exposed via HTTP/REST and gRPC inference endpoints. The root cause is CWE-190 (Integer Overflow or Wraparound), where arithmetic on attacker-influenced integer values exceeds the bounds of the target data type, producing a wrapped value that downstream code treats as valid - commonly leading to undersized allocations, malformed length checks, or out-of-bounds memory operations. In this instance the overflow manifests as a denial of service rather than memory corruption with code execution, suggesting the wrapped value drives Triton into an abort, crash, or resource-exhaustion path rather than a controllable write primitive. The affected CPE is cpe:2.3:a:nvidia:triton_inference_server with the version field wildcarded, indicating NVD has not yet narrowed down the precise vulnerable range.

DescriptionCVE.org
NVIDIA Triton Inference Server contains a vulnerability where an attacker could cause an integer overflow. A successful exploit of this vulnerability might lead to denial of service.
Executive ViewAI
NVIDIA Triton Inference Server contains a remotely exploitable denial-of-service vulnerability requiring no authentication, creating availability risk for organizations running inference workloads. No vendor patch is currently available, requiring immediate network controls to mitigate exposure.
Implement strict network access controls (firewall rules, VPN, bastion hosts) to limit Triton exposure to trusted networks; deploy rate limiting and connection throttling on inference endpoints; establish monitoring for anomalous inference request patterns; restrict administrative APIs to internal-only access.

Attack Technique
Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
