CVE-2023-25523

Local crash via nvdisasm NULL pointer dereference

Published Jul 3, 2023 · Updated Oct 24, 2024

NULL pointer dereference in NVIDIA CUDA Toolkit before 12.2 allows attackers to crash nvdisasm by supplying a malformed ELF file. The nvdisasm ELF parser dereferences a NULL pointer while processing attacker-controlled file data. Exploitation requires a user to run the local command-line tool on the file; the resulting crash interrupts the nvdisasm process.
