amdgpu drm

About this tag
The amdgpu drm tag covers Linux kernel driver issues related to AMD's Direct Rendering Manager (DRM) for graphics and compute. Content includes fixes for GPU page faults after hibernation with PF passthrough, null pointer dereferences in the display stack (CVE-2024-49893, CVE-2025-38361), an array bounds error in MPC combine logic (CVE-2024-26914), and idle reallow path vulnerabilities (CVE-2024-36024). These threads discuss kernel patches, CVE advisories, and operational impacts for systems using AMD GPUs in virtualization, cloud, or enterprise environments.

  1. Linux AMDGPU PF Passthrough Resume Fix Prevents GPU Page Faults

    A narrowly targeted fix in the Linux AMDGPU DRM driver closes a deterministic kernel crash that could occur after hibernation on systems using PF (physical function) passthrough, a change that demands immediate attention from operators who run GPU‑exposed hosts, VMs or containers: the...

  2. CVE-2024-49893: AMD DRM Display Null Pointer DoS Fix in Linux Kernel

    A subtle null‑check omission in the AMD DRM display stack has been cataloged as CVE‑2024‑49893 — a low‑complexity, local NULL pointer dereference that can crash the kernel’s AMD display code path and produce a denial‑of‑service on affected Linux kernels; the fix is a small defensive check in...

  3. CVE-2025-38361: AMD DRM Patch in Linux Kernel and Azure Linux Attestation

    Microsoft’s public advisory for CVE-2025-38361 notes that Azure Linux includes the open‑source library that contains the bug, but that statement is a product‑scoped attestation—not an iron‑clad guarantee that no other Microsoft product ships the same vulnerable code. The Linux kernel fix for...

  4. Azure Linux CVE-2024 36024: Attestation Limits and Exposure Risk

    Microsoft’s public advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for the product inventory Microsoft has completed — but it is not proof that Azure Linux is the only Microsoft product that could possibly include the vulnerable...

  5. Linux Kernel Patch Fixes AMD MPC Array Bounds CVE-2024-26914

    The Linux kernel received a targeted fix for a subtle but potentially disruptive array‑bounds error in the AMD DRM display code: an incorrect constant was used to size the mpc_combine array, allowing an out‑of‑bounds write when a GPU had more planes than the per‑stream limit implied. The issue...
