Lifecycle Timeline
2DescriptionCVE.org
Improper conditions check 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 (Ring 2 device driver layer) allows an unauthenticated adjacent-network attacker to crash or disable the wireless driver with no user interaction. The flaw stems from an improper conditions check (CWE-754) in the driver, yielding complete loss of wireless availability on the affected system and minor downstream availability impact on subsequently connected systems. No public exploit or CISA KEV listing exists at time of analysis, and Intel has published an advisory at INTEL-SA-01422.
Technical ContextAI
Intel PROSet/Wireless WiFi Software for Windows is Intel's full-featured wireless adapter management stack, operating in Ring 2 (the device driver layer between user-space and kernel). The affected component is the Windows kernel-mode WiFi driver (cpe:2.3:a:n/a:intel(r)_proset/wireless_wifi_software_for_windows:*:*:*:*:*:*:*:*), which processes incoming wireless frames and management packets. CWE-754 (Improper Check for Unusual or Exceptional Conditions) indicates the driver fails to correctly validate edge-case conditions in received network data, allowing a specially crafted adjacent-network transmission to trigger an unhandled state that results in driver failure. This class of flaw commonly manifests as a NULL dereference, out-of-bounds access, or unhandled exception in low-level frame-parsing routines that lack defensive boundary checks.
RemediationAI
Apply the updated Intel PROSet/Wireless WiFi Software package as directed by Intel Security Advisory INTEL-SA-01422 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html); the exact patched version must be confirmed from the advisory, as it is not independently specified in available data. As a compensating control while patching is in progress, organizations can restrict access to sensitive systems by using wired Ethernet connections and disabling the Intel wireless adapter in Device Manager on high-value hosts - this removes the attack surface entirely but also eliminates wireless connectivity. Alternatively, deploying 802.1X network access control on wireless infrastructure limits which devices can join the WLAN, effectively raising the bar for adjacent-network exploitation from unauthenticated to credential-bearing. Windows Defender Firewall policies cannot block this attack since it operates at the driver layer below the network stack.
