AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local config-ingestion flaw (AV:L) that hinges on a user loading an attacker-supplied YAML (UI:R); PR:L per vendor, low complexity, and unsafe deserialization yields full code-exec impact (C/I/A:H).

NVIDIA NeMo contains a vulnerability in its dataset-loading workflow where a maliciously crafted model_config.yaml can inject unsafe parameters. A successful exploit of this vulnerability may lead to code execution, data tampering, denial of service, and information disclosure.
Articles & Coverage 1
AnalysisAI
Code execution, data tampering, denial of service, and information disclosure in NVIDIA NeMo Speech (versions 0.0 through 2.9) stem from unsafe deserialization of parameters injected through a maliciously crafted model_config.yaml handled by the dataset-loading workflow. The issue is locally scoped: the assessed vector is CVSS:3.1/AV:L/AC:L/PR:L/UI:R with a base score of 7.8, meaning an attacker with low privileges must place the crafted config where the victim or an automated pipeline will parse it - for example inside a shared or downloaded model bundle or dataset - and exploitation depends on that untrusted NeMo config being loaded. …

Vulnerability AssessmentAI
| Exploitation | Requires the victim to load an attacker-controlled model_config.yaml through NVIDIA NeMo Speech's dataset-loading workflow (affected versions 0.0 through 2.9); the malicious YAML injects unsafe parameters that are deserialized without a safe-loading guard. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but locally-scoped code-execution flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch status is not confirmed from the available intelligence: no fixed version is identified in the provided data, and the references point only to the NVD and CVE.org records plus the NVIDIA product security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5885, which should be consulted for the vendor's stated fixed release and any upgrade guidance for NeMo Speech versions 0.0 through 2.9 - treat that advisory as the primary remediation source rather than an assumed version number. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all NVIDIA NeMo Speech installations running versions 0.0 through 2.9 and identify any dataset-loading workflows that consume model_config.yaml from shared or untrusted sources; immediately restrict such workflows to trusted, verified model bundles only. …
