CVE-2026-41158

Deferred Deferred - Pending Action

GPU Memory Corruption in NVIDIA Driver

Publication date: 2026-06-12

Last updated on: 2026-06-15

Assigner: imaginationtech

Description

Software installed and run as a non-privileged user may conduct GPU system calls to write to arbitrary freed physical pages. Physical memory allocated and freed, without the deferred free mechanism can lead to those resources being used for read/write by the GPU after the kernel module has freed the resource.

Exploitability

CWE

KEV

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability occurs when software running as a non-privileged user makes GPU system calls that allow it to write to arbitrary freed physical memory pages.

Specifically, physical memory that has been allocated and then freed without using a deferred free mechanism can still be accessed for reading or writing by the GPU after the kernel module has released the resource.

Impact Analysis

This vulnerability can lead to unauthorized access or modification of physical memory by GPU operations, potentially allowing malicious software running with limited privileges to manipulate memory that should no longer be accessible.

Such unauthorized memory writes could result in data corruption, information disclosure, or system instability.
