## What is CVE-2025-32003?

CVE-2025-32003 is a medium-severity denial of service vulnerability in 100GbE Intel(R) Ethernet Network Adapter E810, published on 10 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Out-of-bounds read in the firmware for some 100GbE Intel(R) Ethernet Network Adapter E810 before version cvl fw 1.7.6, cpk 1.3.7 within Ring 0: Bare Metal OS may allow a denial of service. Network adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via network access when attack requirements are present with special internal knowledge and requires no 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-125 (Out-of-bounds Read)

Check this codebase for CVE-2025-32003 and fix it if it is affected.

What it is: CVE-2025-32003 is a medium-severity denial of service vulnerability in 100GbE Intel(R) Ethernet Network Adapter E810, published on 10 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-32003 in the wild and no public exploit code.

Affected product: 100GbE Intel(R) Ethernet Network Adapter E810. 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.
