## What is CVE-2022-3028?

CVE-2022-3028 is a high-severity vulnerability in Debian Debian Linux, 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

A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.

Weakness: CWE-787 (Out-of-bounds Write), CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization), CWE-667 (Improper Locking)

## Which versions are affected by CVE-2022-3028?

It affects 3 products.


Products: Debian Debian Linux, Fedoraproject Fedora, Linux kernel.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-3028 and fix it if it is affected.

What it is: CVE-2022-3028 is a high-severity vulnerability in Debian Debian Linux, 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-2022-3028 in the wild and no public exploit code.

Affected product: Debian Debian Linux. 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.
