CVE-2025-20032 is a high-severity vulnerability affecting Intel(R) PROSet/Wireless WiFi Software for Windows versions prior to 23.100. The flaw stems from improper input validation within the software, which is responsible for managing Intel wireless network adapters on Windows platforms. Specifically, this vulnerability allows a privileged local user—such as an administrator or a user with elevated rights—to trigger a denial of service (DoS) condition. The attack vector requires local access, meaning an attacker must already have a foothold on the system with high privileges to exploit this issue. The vulnerability does not require user interaction and can cause significant disruption by impacting the availability of wireless networking capabilities, potentially leading to system instability or network outages. The CVSS 4.0 base score of 8.3 reflects the high impact on availability and integrity, with low attack complexity and no need for authentication beyond existing privileged access. There are no known exploits in the wild as of the publication date, but the presence of this vulnerability in widely deployed Intel wireless management software presents a notable risk, especially in environments where privileged users may be compromised or where insider threats exist. The lack of a patch link in the provided data suggests that remediation may require updating to version 23.100 or later once available or applying vendor-provided mitigations.

For European organizations, the impact of this vulnerability can be significant, particularly in sectors relying heavily on wireless connectivity for critical operations, such as finance, healthcare, manufacturing, and government. A successful DoS attack could disrupt wireless network availability, leading to operational downtime, loss of productivity, and potential cascading effects on business continuity. Since exploitation requires privileged local access, the threat is more pronounced in environments with multiple administrators or where endpoint security is lax, increasing the risk of insider threats or lateral movement by attackers who have already compromised user credentials. Additionally, organizations with remote or hybrid workforces relying on Intel wireless adapters may experience increased exposure. The disruption of wireless connectivity could also affect security monitoring and incident response capabilities if network access is interrupted. Given the widespread use of Intel wireless hardware in laptops and desktops across Europe, the vulnerability poses a broad risk that could affect both private and public sector entities.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Inventory and identify all systems running Intel PROSet/Wireless WiFi Software versions prior to 23.100. 2) Apply the official update to version 23.100 or later as soon as it becomes available from Intel to remediate the vulnerability. 3) Restrict privileged local access strictly to trusted personnel and enforce the principle of least privilege to reduce the risk of exploitation. 4) Implement robust endpoint security controls, including application whitelisting and behavior monitoring, to detect and prevent unauthorized privilege escalation or suspicious activities. 5) Monitor system and network logs for signs of DoS attempts or unusual wireless adapter behavior. 6) Educate administrators and privileged users about the risks of local exploitation and enforce strong authentication and session management practices. 7) Where immediate patching is not feasible, consider temporary workarounds such as disabling the vulnerable wireless management software or restricting its usage through group policies or endpoint management tools. These targeted measures go beyond generic advice by focusing on controlling privileged access and monitoring specific to the Intel wireless software environment.
