CVE-2023-25512

Code execution via malformed cuobjdump input

Published Apr 22, 2023 · Updated Feb 4, 2025

Out-of-bounds read in cuobjdump in NVIDIA CUDA Toolkit before 12.1 allows attackers to execute code via a malformed input file. cuobjdump reads past a memory-buffer boundary while parsing malformed object data; NVIDIA has not identified the affected parser routine. Execution requires a user to run cuobjdump on the crafted file, exposing the process to limited code execution, information disclosure, or a crash.
