CVE-2026-24157

Vulnerability

Overview CVE-2026-24157 is an arbitrary code execution vulnerability in NVIDIA NeMo Framework's checkpoint loading mechanism. The root cause lies in insecure deserialization or mishandling of untrusted checkpoint data during model restoration, which permits an attacker to inject and execute arbitrary code on the affected system [1].

Exploitation

Details To exploit this vulnerability, an attacker would need to supply a malicious checkpoint file—for instance, by enticing a user to load a crafted model or through a supply-chain attack. The attack does not require elevated privileges beyond normal user access to the NeMo Framework. Successful exploitation is achieved when the victim loads the attacker-controlled checkpoint, triggering code execution in the context of the NeMo process [1].

Potential

Impact A successful exploit could allow the attacker to execute arbitrary code, potentially escalating privileges, accessing or modifying sensitive data, and causing denial of service. The scope includes information disclosure and data tampering, making this a high-risk vulnerability for any environment running NeMo with untrusted checkpoints [1].

Mitigation

Status NVIDIA has not yet released a specific patch for this CVE as of the publication date. Users are advised to only load checkpoints from trusted sources, monitor the NeMo GitHub repository [2] for security updates, and apply any patches as soon as they become available. The framework is actively maintained, but the asynchronous release cycle may delay fixes for components under transformation [2].
