CVE-2025-23273

Local service interruption via crafted JPEG division-by-zero

Published Sep 24, 2025 · Updated Sep 24, 2025

Divide-by-zero in NVIDIA CUDA Toolkit before 13.0 and nvJPEG before 13.0.0 allows local users to interrupt JPEG processing. nvJPEG processes a specially crafted JPEG in an undisclosed calculation whose divisor becomes zero; NVIDIA has not identified the responsible function or image field. Exploitation requires local access and user interaction and causes availability loss only, with no reported data disclosure or code execution.
