# CVE-2024-41011: drm/amdkfd: don't allow mapping the MMIO HDP page with large pages

> A flaw in the Linux kernel's AMD GPU driver allows userspace to read unintended MMIO register data due to incorrect page mapping sizes.

- **Severity:** High 7.8 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 18 Jul 2024
- **Updated:** 5 Aug 2026
- **Also known as:** AZL-48820, BELL-CVE-2024-41011, DEBIAN-CVE-2024-41011, GHSA-fv42-492h-89pj, UBUNTU-CVE-2024-41011

## What is CVE-2024-41011?

CVE-2024-41011 is a high-severity vulnerability in Linux kernel, published on 18 Jul 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: don't allow mapping the MMIO HDP page with large pages

We don't get the right offset in that case.  The GPU has
an unused 4K area of the register BAR space into which you can
remap registers.  We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM.  However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

Weakness: CWE-682 (Incorrect Calculation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-41011 and fix it if it is affected.

What it is: CVE-2024-41011 is a high-severity vulnerability in Linux kernel, published on 18 Jul 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-41011 in the wild and no public exploit code.

Affected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
