CVE-2026-24159 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Nvidia Nemo. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 29.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the deserialization vulnerability in NVIDIA NeMo Framework by requiring timely patching and updates as per vendor advisories.
Prevents exploitation of CWE-502 by validating untrusted data inputs prior to deserialization in the framework.
Mitigates remote code execution from deserialization flaws through memory protections like ASLR and DEP.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability enables local low-privileged remote code execution leading to privilege escalation via deserialization (CWE-502), directly mapping to Exploitation for Privilege Escalation (T1068).
NVD Description
NVIDIA NeMo Framework contains a vulnerability where an attacker may cause remote code execution. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure and data tampering.
Deeper analysisAI
CVE-2026-24159 is a vulnerability in the NVIDIA NeMo Framework that enables an attacker to cause remote code execution. A successful exploit might lead to code execution, escalation of privileges, information disclosure, and data tampering. The issue has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is linked to CWE-502, which involves deserialization of untrusted data.
Exploitation requires local access, low attack complexity, and low privileges, with no user interaction needed. A local attacker meeting these conditions can achieve high impacts across confidentiality, integrity, and availability, potentially resulting in the described outcomes of code execution, privilege escalation, information disclosure, and data tampering.
