Attack-Flow Graph

Executive Summary

This vulnerability is a NULL pointer dereference in the Linux kernel's AMD DRM (Direct Rendering Manager) component, specifically in the function ras_core_ras_interrupt_detected().

The issue occurs when the ras_core pointer is NULL, but the code attempts to access ras_core->dev in an error handling path, leading to a NULL pointer dereference.

Impact Analysis

A NULL pointer dereference in the kernel can cause the affected system to crash or become unstable, potentially leading to a denial of service.
