Lifecycle Timeline
2DescriptionCVE.org
Improper buffer restrictions for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.
AnalysisAI
Denial of service in Intel PROSet/Wireless WiFi Software for Windows stems from improper buffer restrictions (CWE-119) in the Ring 2 device driver layer, exploitable by an adjacent network attacker without authentication or user interaction. An attacker within Wi-Fi range or on the same network segment can trigger a driver-level crash by sending crafted wireless input, resulting in high availability impact on the target system and low availability impact on subsequent systems, with no confidentiality or integrity consequences. No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog at time of analysis.
Technical ContextAI
The vulnerability resides in the Ring 2 (kernel-mode device driver) layer of Intel PROSet/Wireless WiFi Software for Windows. In x86 architecture, Ring 2 maps to kernel-space driver execution on Windows, meaning the vulnerable code runs with elevated OS privilege. CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) indicates the driver fails to enforce proper boundary checks when processing network-sourced data - most likely malformed Wi-Fi management frames or data frames received over the air. A buffer boundary violation in a kernel-mode driver can corrupt kernel memory structures, triggering a system crash (BSOD) or rendering the wireless subsystem non-functional. The CPE string cpe:2.3:a:n/a:intel(r)_proset/wireless_wifi_software_for_windows:*:*:*:*:*:*:*:* uses a wildcard version field, indicating the advisory covers the product broadly without a documented lower version bound - precise affected version ranges must be confirmed via INTEL-SA-01422.
RemediationAI
The primary remediation is to apply the patched driver version identified in Intel Security Advisory INTEL-SA-01422, available at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html. The exact fixed version is not independently confirmed from available data - patch availability is per Intel vendor advisory only, and administrators should verify the specific update package from Intel's advisory before deploying. As a compensating control where patching is not immediately possible, uninstalling Intel PROSet/Wireless Software and relying on the Windows built-in Wi-Fi driver stack removes the vulnerable driver code path entirely, though this trade-off eliminates Intel's advanced wireless management, enterprise policy, and diagnostic features. Additionally, configuring Windows Defender Firewall or network policies to restrict device connectivity to trusted Wi-Fi networks and disabling automatic connection to open or unknown SSIDs reduces the adjacent network exposure surface, limiting the pool of potential attackers who can reach the vulnerable driver.
