About this tag
CVE-2024-41011 is a Linux kernel vulnerability in the AMD Kernel Fusion Driver (KFD) that causes excessive MMIO mapping on systems with page sizes larger than 4 KB. This exposes a full PAGE_SIZE of device MMIO instead of the intended single 4 KB HDP register window, potentially allowing dangerous access to GPU register space. The issue was fixed upstream in July 2024 and backported by distributions. Unpatched systems with AMD GPUs and the KFD/AMDGPU driver remain at risk. This tag covers discussions about the bug, its impact, and patching guidance for affected Linux systems.

  1. CVE-2024-41011: Linux AMD KFD MMIO Mapping Bug and Patch Guide

    A subtle mapping bug in the Linux kernel’s AMD Kernel Fusion Driver (KFD) — tracked as CVE-2024-41011 — can cause the driver to map more MMIO (memory‑mapped I/O) space than intended on systems that use page sizes larger than 4 KB, exposing a full PAGE_SIZE of device MMIO instead of the single 4...
