## What is CVE-2022-1247?

CVE-2022-1247 is a high-severity vulnerability in Fedoraproject Fedora, published on 31 Aug 2022. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An issue found in linux-kernel that leads to a race condition in rose_connect(). The rose driver uses rose_neigh->use to represent how many objects are using the rose_neigh. When a user wants to delete a rose_route via rose_ioctl(), the rose driver calls rose_del_node() and removes neighbours only if their “count” and “use” are zero.

Weakness: CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-1247 and fix it if it is affected.

What it is: CVE-2022-1247 is a high-severity vulnerability in Fedoraproject Fedora, published on 31 Aug 2022. 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-2022-1247 in the wild and no public exploit code.

Affected product: Fedoraproject Fedora. 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.
