Received Received - Intake
GPU Write Use-After-Free in NVIDIA GPU Driver

Publication date: 2026-06-19

Description
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources creating a write use after free scenario. A shared resource (memory page) managed by a CPU thread of control (driver) and accessed by a GPU thread of control (Firmware) can cause a write UAF when the CPU thread frees the resource before the GPU FW has finished accessing it.

CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability occurs when software running as a non-privileged user makes improper GPU system calls that lead to mismanagement of resources. Specifically, a shared memory page managed by the CPU driver and accessed by the GPU firmware can be freed by the CPU before the GPU has finished using it, causing a write use after free (UAF) scenario.

Impact Analysis

The vulnerability can lead to memory corruption due to the write use after free condition. This may cause instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges by exploiting the improper resource management between CPU and GPU threads.
