CVE-2025-20006 is a high-severity vulnerability affecting Intel(R) PROSet/Wireless WiFi Software for Windows versions prior to 23.100. The flaw is a use-after-free condition that can be triggered by an unauthenticated attacker with adjacent access, meaning the attacker must be on the same local network segment or have some form of network proximity to the target device. Exploiting this vulnerability allows the attacker to cause a denial of service (DoS) condition, effectively disrupting the wireless connectivity of the affected system. The vulnerability does not require any user interaction or privileges, making it easier to exploit in environments where the attacker can gain adjacent network access. The CVSS 4.0 score of 8.3 reflects the high impact on availability (denial of service) with low attack complexity and no authentication required. The vulnerability does not impact confidentiality or integrity directly but can severely affect availability, potentially disrupting business operations reliant on wireless connectivity. Intel PROSet/Wireless WiFi Software is a widely used driver and management suite for Intel wireless adapters on Windows platforms, often deployed in enterprise and consumer environments. The use-after-free bug indicates a memory management error where the software attempts to use memory after it has been freed, leading to instability and crashes. No known exploits are currently reported in the wild, but the high severity and ease of exploitation make timely patching critical once updates are available. The lack of a patch link in the provided data suggests that remediation may still be pending or in progress as of the publication date.

For European organizations, this vulnerability poses a significant risk to network availability, especially in environments heavily reliant on Intel wireless adapters and the PROSet software for WiFi management. Disruption of wireless connectivity can impact critical business functions, including remote work, communications, and access to cloud services. Industries such as finance, healthcare, manufacturing, and government agencies that depend on stable wireless networks could experience operational downtime, loss of productivity, and potential cascading effects on other systems. The fact that exploitation requires only adjacent network access means that attackers could leverage compromised devices within the same network segment or physically nearby to launch attacks, increasing the risk in shared office spaces, public WiFi environments, and large corporate campuses. Additionally, denial of service attacks could be used as a diversion tactic or to facilitate further attacks by degrading network defenses. The vulnerability's presence in widely deployed Intel wireless software means that many endpoints across Europe could be affected, amplifying the potential scale of impact.

European organizations should prioritize the following mitigation steps: 1) Monitor Intel's official channels for the release of patches addressing CVE-2025-20006 and apply updates immediately upon availability to affected systems running Intel PROSet/Wireless WiFi Software before version 23.100. 2) Implement network segmentation to limit adjacent access exposure, restricting wireless network access to trusted devices and users only. 3) Employ network access control (NAC) solutions to enforce device compliance and reduce the risk of unauthorized devices gaining adjacent network access. 4) Use wireless intrusion detection and prevention systems (WIDS/WIPS) to detect anomalous activity that could indicate exploitation attempts. 5) Educate IT staff and users about the risks of connecting to untrusted wireless networks and the importance of reporting connectivity issues promptly. 6) As a temporary workaround before patching, consider disabling or restricting the use of Intel PROSet/Wireless WiFi Software features if feasible, or use alternative wireless management tools where possible. 7) Maintain up-to-date endpoint protection and monitoring to detect potential denial of service conditions or related network disruptions.
