NVIDIA Triton Inference Server for Linux contains a vulnerability where an attacker can cause uncontrolled resource consumption. A successful exploit of this vulnerability might lead to denial of service.
Articles & Coverage 1
AnalysisAI
Denial of service in NVIDIA Triton Inference Server for Linux lets remote unauthenticated attackers exhaust server resources (CWE-400 uncontrolled resource consumption) and render the AI/ML inference endpoint unavailable, with no impact to confidentiality or integrity. The CVSS 3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/A:H), reflecting network-reachable, low-complexity, no-privilege exploitation. …

Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no special conditions - remote unauthenticated exploitation against network-reachable instances of NVIDIA Triton Inference Server for Linux. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector is internally consistent for a DoS: AV:N (network), AC:L (low complexity), PR:N (no privileges), UI:N (no interaction), S:U, with A:H and C:N/I:N - a clean availability-only impact scoring 7.5 (High). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach an internet- or network-exposed Triton endpoint sends a crafted or high-volume sequence of inference/API requests that the server processes without an effective resource bound, driving CPU/memory/thread usage until the service stops responding. Because exploitation requires no authentication and no user interaction (PR:N/UI:N) and is low-complexity (AC:L), the attack is repeatable and cheap; no public exploit code is currently identified, but the low barrier makes independent development straightforward. |
| Remediation | No vendor-released patch version was identified in the provided data, so consult the NVIDIA product security advisory for CVE-2026-47479 (referenced via https://nvd.nist.gov/vuln/detail/CVE-2026-47479) and upgrade Triton Inference Server to the fixed release NVIDIA specifies. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all NVIDIA Triton Inference Server instances, document version numbers, implement network-level rate limiting or Web Application Firewall rules to restrict incoming request rates, and activate real-time monitoring and alerting for resource utilization anomalies (CPU, memory, network I/O). …
