CVE-2026-24243

Local code execution via untrusted data deserialization

Published Jul 1, 2026 · Updated Jul 1, 2026

Untrusted deserialization in NVIDIA Megatron Bridge before 0.4.1 allows local users to execute code through crafted input. NVIDIA's advisory does not identify the affected component, deserialization API, data format, or unsafe operation beyond processing untrusted serialized data. Exploitation requires user interaction with attacker-controlled input and executes code in the processing user's context, enabling privilege escalation and access to or modification of data.
