Severity by source
AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Local unsafe deserialization requires the victim to load attacker data (AV:L/UI:R), needs no attacker auth (PR:N), and yields full code execution (C:H/I:H/A:H) in the user's context (S:U).

Lifecycle Timeline
3DescriptionCVE.org
NVIDIA NeMo Speech for all platforms contains a vulnerability where malicious data created by an attacker could cause remote code execution. A successful exploit of this vulnerability might lead to code execution, information disclosure, and data tampering.
Articles & Coverage 1
AnalysisAI
Code execution, information disclosure, and data tampering are possible in NVIDIA NeMo Speech versions 0.0 through 2.9 due to unsafe deserialization of untrusted data. Exploitation requires the victim to load attacker-crafted serialized data (dataset, manifest, or model checkpoint) on their own machine, making this a local, user-interaction-dependent flaw (AV:L/UI:R) that runs with the victim's privileges. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-crafted NeMo Speech data (a serialized dataset, manifest, or model checkpoint) into the toolkit on their own machine - this is the CWE-502 deserialization trigger and the UI:R user-interaction requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but access-limited 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 | No vendor-released patch has been identified at time of analysis; monitor the NVIDIA product security advisory (https://github.com/NVIDIA/product-security/tree/main/2026/5885) for updates. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all deployments of NVIDIA NeMo Speech versions 0.0 through 2.9 and instruct users to stop loading untrusted datasets, manifests, or model checkpoints; isolate any necessary processing in a sandboxed VM, container, or low-privilege account without access to sensitive data or production credentials. …
