Local vector because exploitation requires a victim to load malicious data into the Explorer (UI:R); no auth needed (PR:N); unsafe deserialization yields full code execution, so C/I/A all High.

3DescriptionCVE.org
NVIDIA NeMo Speech for all platforms contains a vulnerability in the speech data explorer component, where malicious data created by an attacker could cause remote code execution. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.

AnalysisAI
Deserialization of untrusted data in the NVIDIA NeMo Speech 'Speech Data Explorer' component (affected versions 0.0 through 2.9, all platforms) lets an attacker who supplies crafted malicious data achieve code execution in the context of the user running the tool, with follow-on privilege escalation, information disclosure, and data tampering. The flaw requires no authentication on the target (PR:N) but is local in reach (AV:L) and depends on user interaction (UI:R) - a user must actively open or load the attacker-crafted dataset, manifest, or serialized artifact inside the Explorer, which confines exposure to developers and researchers running NeMo rather than production network services. …

Vulnerability AssessmentAI
| Exploitation | Requires the victim to load or open attacker-crafted malicious data (dataset/manifest/serialized artifact) within the NVIDIA NeMo Speech 'Speech Data Explorer' component (affected NeMo Speech 0.0 through 2.9). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 7.8) describes a LOCAL, low-complexity, unauthenticated but user-interaction-dependent deserialization flaw (CWE-502) - not a remotely reachable service bug. … 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 version is confirmed in the available data for CVE-2026-24267; the authoritative remediation guidance is expected in the NVIDIA product-security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5885, which should be consulted for the exact fixed NeMo Speech release before upgrading - do not assume a specific version number in the absence of that confirmation. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all installations of NVIDIA NeMo Speech 'Speech Data Explorer' versions 0.0 through 2.9 across all platforms and instruct developers and researchers to stop opening untrusted datasets, manifests, or serialized artifacts in the tool; restrict data loading to trusted sources and run the Explorer with least privilege. …
