CVE-2026-24228 is a deserialization of untrusted data vulnerability (CWE-502) in the NVIDIA NeMo Framework for Linux. A successful exploit may lead to arbitrary code execution, privilege escalation, data tampering, and information disclosure. All NeMo Framework versions from 0.0 through 2.7.2 are affected; version 2.7.3 introduces the fix. The vulnerability was disclosed on June 16, 2026, with a CVSS v3.1 base score of 7.8 (High), assigned by NVIDIA Corporation (Github Advisory, NVIDIA Advisory).

The root cause is improper deserialization of untrusted data (CWE-502), mapped to CAPEC-586 (Object Injection). An attacker with low-level local privileges can supply crafted serialized data to the NeMo Framework, which processes it without sufficient validation, allowing the injected object to trigger arbitrary code execution upon deserialization. The attack vector is local, requires low privileges, no user interaction, and has low complexity, making it straightforward to exploit once local access is obtained. No public proof-of-concept or detailed technical write-up has been published as of the disclosure date (Github Advisory, NVIDIA Advisory).

Successful exploitation allows a low-privileged local attacker to execute arbitrary code in the context of the NeMo Framework process, potentially escalating privileges on the affected Linux system. All three security pillars are fully compromised: confidentiality (sensitive data and model artifacts exposed), integrity (data and model tampering), and availability (service disruption). In AI/ML pipeline environments where NeMo is deployed, this could enable an attacker to poison training data, exfiltrate proprietary models, or pivot to other components of the AI infrastructure (NVIDIA Advisory, Github Advisory).

NVIDIA has released NeMo Framework version 2.7.3 as the patched release, addressing all versions from 0.0 through 2.7.2. Organizations should upgrade to version 2.7.3 or later as the primary remediation step. As interim mitigations, restrict file access and serialized data inputs to trusted sources only, implement input validation for deserialization operations, and monitor NeMo Framework deployments for suspicious deserialization activity (NVIDIA Advisory, Github Advisory).

Coverage of CVE-2026-24228 appeared across multiple security news outlets shortly after disclosure, including GBHackers, SecurityOnline, CyberPress, and UnderCodeNews, which noted it as part of a broader set of high-severity flaws affecting NVIDIA NeMo's AI infrastructure. Social media activity was observed on Mastodon and Bluesky, with security community accounts flagging the vulnerability. Coverage framed the issue in the context of growing AI/ML supply chain security concerns, noting that NeMo is widely used in enterprise AI pipelines (GBHackers, SecurityOnline, UnderCodeNews).
