CVE-2026-24152

Code execution via malicious checkpoint deserialization

Published Mar 24, 2026 · Updated Mar 24, 2026

Deserialization of untrusted data in NVIDIA Megatron-LM before 0.15.3 allows attackers to execute code via a malicious checkpoint. NVIDIA identifies checkpoint loading and CWE-502 but has not disclosed the affected routine or exact unsafe deserialization operation. Exploitation requires a crafted checkpoint to be loaded, after which code runs with the loading process's privileges and can disclose or alter data.
