Summary

CVE-2026-24146 is a high-severity Memory Allocation with Excessive Size Value (CWE-789) vulnerability in Nvidia Triton Inference Server. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 20.8th 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 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Application or System Exploitation (T1499.004). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the insufficient input validation that allows large numbers of outputs to trigger uncontrolled memory allocation and server crash.

SC-5 Denial-of-service Protection good match

preventdetect

Protects against denial-of-service attacks by limiting the effects of resource exhaustion from malformed inputs causing server crashes.

SI-2 Flaw Remediation good match

prevent

Ensures timely identification, reporting, and patching of the specific flaw in NVIDIA Triton Inference Server leading to DoS.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact

Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.

NVD Description

NVIDIA Triton Inference Server contains a vulnerability where insufficient input validation and a large number of outputs could cause a server crash. A successful exploit of this vulnerability might lead to denial of service.

Deeper analysisAI

CVE-2026-24146 is a vulnerability in NVIDIA Triton Inference Server stemming from insufficient input validation combined with a large number of outputs, which can trigger a server crash. This issue, classified under CWE-789 (Uncontrolled Memory Allocation), 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.

A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation results in denial-of-service, causing the server to crash and potentially disrupting inference services until restart.
