CVE-2025-30255 is a vulnerability identified in Intel PROSet/Wireless WiFi Software for Windows, specifically in versions before 23.160. The flaw is an out-of-bounds write occurring within the device driver operating at Ring 2 privilege level, which is a kernel-mode driver responsible for managing wireless network interfaces. This vulnerability can be exploited by an unprivileged, unauthenticated attacker with low attack complexity, requiring only adjacent network access—meaning the attacker must be on the same local network segment as the target device. No user interaction or special internal knowledge is necessary to trigger the flaw. The out-of-bounds write can cause the wireless driver or the entire system to crash, leading to a denial of service (DoS) condition. The CVSS 4.0 score of 8.3 reflects a high severity, with the attack vector being adjacent network (AV:A), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on availability (VA:H). The vulnerability does not significantly affect confidentiality or integrity but can severely disrupt availability, potentially causing system reboots or loss of wireless connectivity. No public exploits have been reported yet, but the vulnerability is published and should be addressed promptly. The affected product is widely used in Windows environments with Intel wireless adapters, making it relevant for many enterprise and consumer systems.

For European organizations, the primary impact is on system availability, potentially causing wireless network disruptions or system crashes. This can affect business continuity, especially in environments relying heavily on wireless connectivity for critical operations, such as offices, manufacturing plants, healthcare facilities, and public services. The denial of service could lead to loss of productivity, interrupted communications, and potential cascading effects on other network-dependent services. Since the attack requires adjacent access, organizations with open or poorly segmented wireless networks are at higher risk. Confidentiality and integrity impacts are minimal, but the availability impact is high, which can indirectly affect operational security and service reliability. The lack of required privileges or user interaction lowers the barrier for attackers, increasing the risk in shared or public wireless environments. European enterprises with extensive Intel wireless hardware deployments are particularly vulnerable until patches are applied.

1. Immediately plan and deploy updates to Intel PROSet/Wireless WiFi Software version 23.160 or later once available from Intel's official channels. 2. Implement strict network segmentation to limit adjacent network access, especially in wireless networks, restricting access to trusted devices only. 3. Employ network access control (NAC) solutions to authenticate and authorize devices before granting network connectivity. 4. Monitor wireless network traffic for unusual patterns that may indicate attempts to exploit this vulnerability. 5. Disable or restrict wireless interfaces on critical systems where feasible until patches are applied. 6. Educate IT staff about the vulnerability and ensure rapid incident response capabilities in case of denial of service events. 7. Maintain an inventory of devices using Intel wireless adapters and prioritize patching based on criticality and exposure. 8. Use endpoint detection and response (EDR) tools to detect abnormal driver crashes or system reboots that may indicate exploitation attempts.
