- **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:** 12 Mar 2015
- **Updated:** 6 Aug 2024

## What is CVE-2015-2150?

CVE-2015-2150 is a medium-severity denial of service vulnerability in Linux kernel, published on 12 Mar 2015. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.

Weakness: CWE-264

## Which versions are affected by CVE-2015-2150?

It affects 3 products.


Products: Linux kernel, Ubuntu Ubuntu, Xen Xen.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2015-2150 and fix it if it is affected.

What it is: CVE-2015-2150 is a medium-severity denial of service vulnerability in Linux kernel, published on 12 Mar 2015. 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-2015-2150 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.
