AMD Radeon™ Graphics Driver Shader Vulnerability

Summary

A researcher has reported an out of bounds memory access vulnerability in the AMD Radeon™ user mode drivers for DirectX® and Vulkan®. The researcher demonstrated that the issue can be triggered by supplying a specially crafted malicious shader through a web browser's WebGPU interface, which they report can result in an out of bounds read or write. The researcher claims this could potentially lead to a loss of integrity or a denial of service.

AMD has analyzed the report and concluded that the reported behavior is reproducible and that the observed outcome is a crash of the affected process, resulting in a denial of service. AMD was not able to identify a method of leveraging this issue to achieve any impact beyond loss of availability and encourages users to maintain safe computing practices and only click on links from known, trusted sources.
