Data disclosure and service interruption via integer overflow
Published Dec 30, 2022 · Updated Apr 23, 2025
Integer overflow in nvidia.ko in NVIDIA vGPU Software allows local users to disclose or alter data or interrupt service. The Linux kernel-mode module performs an undisclosed integer calculation without preventing overflow; NVIDIA has not published the affected function, input field, or resulting memory operation. A local low-privileged account is required, and successful exploitation is bounded to limited data exposure or modification or a service interruption.
