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.
