CVE-2025-23339

Code execution via malicious ELF parsing

Published Sep 24, 2025 · Updated Sep 24, 2025

Stack-based buffer overflow in NVIDIA CUDA Toolkit before 13.0 allows attackers to execute code through a malicious ELF file. The cuobjdump ELF-processing path overruns a stack buffer while handling attacker-controlled file contents; NVIDIA has not disclosed the affected function. Execution requires a user to run cuobjdump on the file, and resulting code runs with that user's privileges.
