## What is CVE-2025-31146?

CVE-2025-31146 is a medium-severity vulnerability in Intel Ethernet Adapter Complete Driver Pack software, published on 11 Nov 2025. 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

Time-of-check time-of-use race condition for some Intel Ethernet Adapter Complete Driver Pack software before version 1.5.1.0 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Weakness: CWE-367 (Time-of-check Time-of-use (TOCTOU) Race Condition)

Check this codebase for CVE-2025-31146 and fix it if it is affected.

What it is: CVE-2025-31146 is a medium-severity vulnerability in Intel Ethernet Adapter Complete Driver Pack software, published on 11 Nov 2025. 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-2025-31146 in the wild and no public exploit code.

Affected product: Intel Ethernet Adapter Complete Driver Pack software. 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.
