No technical details, affected product versions, or exploit information have been published. The absence of a CVSS score and patch links further supports that this is not an active or confirmed vulnerability. Without concrete data on the nature of the vulnerability, its attack vector, or impact, it is not possible to provide a detailed technical explanation. The rejection status typically means that security teams should deprioritize this CVE and focus on confirmed vulnerabilities.

Since CVE-2025-64478 is rejected and lacks any technical or exploit information, there is no known impact on confidentiality, integrity, or availability. European organizations are not at risk from this entry as it does not represent a valid or exploitable vulnerability.
