NVIDIA NeMo Speech 3.0 Fixes Five Code Execution Flaws
Tech GuruQuick Answer
NVIDIA bulletin 5885 updates NeMo Speech to version 3.0 or later for five vulnerabilities affecting versions 0.0 through 2.9 on all platforms. Treat external datasets, model configuration and serialized tokenizer files as security-sensitive inputs when planning the update.
Confirm Scope And Apply The Supported Fix
What to do now: Identify NeMo Speech environments and the source of their models and datasets, update the installed runtime to the supported fixed release, and redeploy jobs or services that still use the old environment.
Source check: 2026-10-02 UTC. This notice reflects the primary-source evidence described below, not a completed update or exploitation test. Recheck the advisory and supported distribution channel before changing production.
Scope And Authority
| Product scope | NVIDIA NeMo Speech on all platforms through version 2.9 |
|---|---|
| Advisory | NVIDIA Security Bulletin 5885 |
| CVEs | CVE-2026-24239, CVE-2026-24267, CVE-2026-65111, CVE-2026-65178, CVE-2026-65179 |
| Authoritative release date | 2026-09-22 (NVIDIA CSAF initial release; title still says August 2026) |
| Authority revision date | 2026-09-22, revision 1.0.0 Initial Release; no independently verified sub-day publication time. |
| Affected versions | NVIDIA NeMo Speech versions 0 through 2.9 on all platforms. |
| Fixed version | NVIDIA NeMo Speech 3.0 |
| CVSS base score | 7.8 / 8.8 (CVSS v3.1) |
| CVSS severity | High |
| Exploitation status | NVIDIA bulletin 5885 does not state that these flaws are being exploited. That is not confirmation that exploitation has not occurred. |
What Changed
The issues include code execution from malicious data, unsafe parameters in model_config.yaml, and TabularTokenizer loading an attacker-controlled .pkl file through pickle. Some vectors require local access or user interaction; the bulletin does not establish that every NeMo service is remotely exploitable without interaction.
What To Validate Now
- Inventory. Record NeMo Speech runtime versions, containers or virtual environments, dataset/model ingestion paths and job owners.
- Establish applicability. Compare each deployment with the authority's affected-version statement: NVIDIA NeMo Speech versions 0 through 2.9 on all platforms. Do not infer applicability from product family or severity alone.
- Remediate. Update NeMo Speech to 3.0 or later through NVIDIA's supported repository and rebuild/redeploy affected environments as needed. Upgrading does not make an arbitrary external pickle or model configuration trustworthy.
- Validate. Record the runtime version actually used by training/inference jobs, then test representative speech workflows and trusted model/tokenizer loading. Confirm that scheduled jobs and containers are not still pinned to older dependencies.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
