# CVE-2013-7445: Denial of service in n/a

> Local attackers can cause denial of service via memory consumption in the Linux kernel DRM subsystem by triggering excessive GEM object requests through graphics applications.

- **Severity:** High 7.8 (`AV:N/AC:L/Au:N/C:N/I:N/A:C`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only

- **Also known as:** DEBIAN-CVE-2013-7445, GHSA-j587-gvrg-27rp, ROOT-OS-DEBIAN-11-CVE-2013-7445, ROOT-OS-DEBIAN-12-CVE-2013-7445, ROOT-OS-DEBIAN-13-CVE-2013-7445, ROOT-OS-UBUNTU-2204-CVE-2013-7445, ROOT-OS-UBUNTU-2404-CVE-2013-7445, UBUNTU-CVE-2013-7445

## What is CVE-2013-7445?

CVE-2013-7445 is a high-severity denial of service vulnerability in Linux kernel, published on 16 Oct 2015. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

The Direct Rendering Manager (DRM) subsystem in the Linux kernel through 4.x mishandles requests for Graphics Execution Manager (GEM) objects, which allows context-dependent attackers to cause a denial of service (memory consumption) via an application that processes graphics data, as demonstrated by JavaScript code that creates many CANVAS elements for rendering by Chrome or Firefox.

Weakness: CWE-399

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2013-7445 and fix it if it is affected.

What it is: CVE-2013-7445 is a high-severity denial of service vulnerability in Linux kernel, published on 16 Oct 2015. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2013-7445 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.
