## What is CVE-2025-14525?

CVE-2025-14525 is a medium-severity denial of service vulnerability in Red Hat OpenShift Virtualization 4, published on 26 Jan 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A flaw was found in kubevirt. A user within a virtual machine (VM), if the guest agent is active, can exploit this by causing the agent to report an excessive number of network interfaces. This action can overwhelm the system's ability to store VM configuration updates, effectively blocking changes to the Virtual Machine Instance (VMI). This allows the VM user to restrict the VM administrator's ability to manage the VM, leading to a denial of service for administrative operations.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)

Check this codebase for CVE-2025-14525 and fix it if it is affected.

What it is: CVE-2025-14525 is a medium-severity denial of service vulnerability in Red Hat OpenShift Virtualization 4, published on 26 Jan 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-2025-14525 in the wild and no public exploit code.

Affected packages and fixed versions:
- kubevirt.io/kubevirt (Go): affected all versions; no fix listed
- kubevirt.io/kubevirt (Go): affected all versions up to 1.7.0; no fix listed
- kubevirt.io/kubevirt (Go): affected all versions up to 1.7.0; no fix listed

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.
