# NVIDIA GPU driver: integer overflow lets local user write past GPU buffers

Link for people: https://infrastack.ai/live/CVE-2026-49747 (this .md is for agents)

A non-privileged program can issue GPU system calls that map a GPU buffer larger than 4GB, which overflows an integer and corrupts an array length. The result is out-of-bounds writes to GPU buffers, which can crash the kernel or read and write memory the program should not reach.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Software installed and run as a non-privileged user may conduct GPU system calls to trigger an integer overflow and allow OOB writes to GPU buffers.



The integer overflow caused when mapping a GPU buffer >4GB causes corruption of array length, and can lead to kernel panics or out of bounds access.
