CVE-2026-24159: 
Python vulnerability analysis and mitigation

CVE-2026-24159 is a deserialization of untrusted data vulnerability (CWE-502) in the NVIDIA NeMo Framework that enables remote code execution. It affects all NeMo Framework versions prior to 2.6.2. The vulnerability was published on March 24, 2026, with NIST's initial analysis completed on March 30, 2026. NVD assigns a CVSS v3.1 base score of 9.8 (Critical), while NVIDIA's own CNA scoring yields 7.8 (High) using a local attack vector (NVD, NVIDIA Advisory).

The root cause is improper deserialization of untrusted data (CWE-502), classified under CAPEC-586 (Object Injection), within the NVIDIA NeMo Framework. An attacker can exploit this by supplying a maliciously crafted serialized payload to the framework, which — when deserialized — triggers arbitrary code execution on the host system. NVD's enriched scoring reflects a network-accessible, unauthenticated, zero-interaction attack path (AV:N/AC:L/PR:N/UI:N), while NVIDIA's own vector suggests a local privilege context (AV:L/PR:L), indicating the precise attack surface may depend on how NeMo processes external data inputs (NVD, NVIDIA Advisory). No public proof-of-concept code has been identified at this time.

Successful exploitation can result in arbitrary remote code execution, privilege escalation, information disclosure, and data tampering on systems running vulnerable NeMo Framework versions. Given NeMo's role as an AI/ML development framework often deployed in research and enterprise AI pipelines, compromise could expose sensitive model data, training datasets, and infrastructure credentials. The HIGH impact across confidentiality, integrity, and availability underscores the potential for full system compromise and lateral movement within AI development environments (NVD, CyberSecurityNews).

As of the time of reporting, there is no public proof-of-concept exploit and no confirmed evidence of in-the-wild exploitation (Feedly). The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.00116 (0.116%), indicating a currently low probability of exploitation in the near term. However, the network-accessible, no-authentication-required attack vector (per NVD's scoring) makes this a high-priority patching target if NeMo endpoints are exposed (NVD).

NVIDIA has released a patch in NeMo Framework version 2.6.2, which resolves this vulnerability. Organizations should immediately upgrade all NeMo Framework deployments to version 2.6.2 or later. As an interim measure, restrict network access to NeMo Framework services and ensure they are not exposed to untrusted networks or the public internet. No alternative workarounds have been publicly documented by NVIDIA (NVIDIA Advisory, NVD).

Security news outlets including GBHackers, CyberPress, and CyberSecurityNews covered the vulnerability as part of broader reporting on critical NVIDIA AI framework flaws enabling RCE and DoS attacks (GBHackers, CyberPress, CyberSecurityNews). Community aggregators such as VulDB and CVEFeed.io indexed the vulnerability shortly after disclosure. No notable individual researcher commentary or significant social media debate has been identified beyond standard CVE tracking activity.
