## What is CVE-2025-31948?

CVE-2025-31948 is a medium-severity denial of service vulnerability in Intel(R) oneAPI Math Kernel Library, published on 11 Nov 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Improper input validation for some Intel(R) oneAPI Math Kernel Library before version 2025.2 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 local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Weakness: CWE-20 (Improper Input Validation)

Check this codebase for CVE-2025-31948 and fix it if it is affected.

What it is: CVE-2025-31948 is a medium-severity denial of service vulnerability in Intel(R) oneAPI Math Kernel Library, published on 11 Nov 2025. 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-2025-31948 in the wild and no public exploit code.

Affected product: Intel(R) oneAPI Math Kernel Library. 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.
