Summary

CVE-2026-24266 is a medium-severity Use After Free (CWE-416) vulnerability in Nvidia Triton Inference Server. Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-2 (Flaw Remediation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Vulnerability Data

NVIDIA Triton Inference Server for Linux contains a vulnerability where an attacker can cause a use-after-free issue. A successful exploit of this vulnerability might lead to denial of service.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
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.
Why these techniques?

Use-after-free in public-facing Triton server directly enables remote exploitation leading to application DoS.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires timely remediation of the identified use-after-free flaw in Triton Inference Server before exploitation occurs.

prevent

Implements memory protections that can block or contain exploitation of use-after-free conditions leading to denial of service.

prevent

Provides denial-of-service protection mechanisms that limit the impact of a successful use-after-free crash in the inference server.
