## What is CVE-2011-0711?

CVE-2011-0711 is a low-severity vulnerability in Linux kernel, published on 1 Mar 2011. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The xfs_fs_geometry function in fs/xfs/xfs_fsops.c in the Linux kernel before 2.6.38-rc6-git3 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FSGEOMETRY_V1 ioctl call.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2011-0711 and fix it if it is affected.

What it is: CVE-2011-0711 is a low-severity vulnerability in Linux kernel, published on 1 Mar 2011. 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-2011-0711 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.
