Lifecycle Timeline
2DescriptionCVE.org
Improper conditions check for some Intel(R) PROSet/Wireless WiFi Software 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 (high) impacts.
AnalysisAI
Denial of service in Intel PROSet/Wireless WiFi Software affects the Ring 2 device driver layer, where an improper conditions check (CWE-754) can be triggered by an adjacent, unauthenticated attacker with no user interaction required. The vulnerability collapses wireless availability on the affected host and, per the CVSS 4.0 vector, cascades to subsequent system availability as well, meaning dependent network-connected services may also be disrupted. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Technical ContextAI
The flaw resides in the Ring 2 device driver layer of Intel PROSet/Wireless WiFi Software - the ring that encompasses hardware device drivers operating below OS user space but above the hardware abstraction layer. CWE-754 (Improper Check for Unusual or Exceptional Conditions) indicates the driver fails to validate or handle anomalous conditions arising from adjacent network traffic, causing a fault that degrades or terminates wireless availability. The CPE string (cpe:2.3:a:n/a:intel(r)_proset/wireless_wifi_software:*:*:*:*:*:*:*:*) covers all versions with no upper bound, suggesting broad version scope. The adjacent attack vector means the attacker must be on the same broadcast domain or physical link segment as the target - typical Wi-Fi proximity attack surface.
RemediationAI
Consult the Intel security advisory INTEL-SA-01422 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html) for the vendor-confirmed patched version - an exact fix version is not independently confirmed from the available input data. As a compensating control where patching is not immediately possible, restricting the device's association to trusted, access-controlled Wi-Fi networks reduces exposure by limiting adjacency; however, this does not eliminate risk if attackers can gain proximity to the same segment. Disabling Intel PROSet/Wireless software's advanced features or switching to a basic OS-native driver may reduce attack surface, at the cost of losing vendor-specific management and performance features. Enterprise environments should prioritize endpoints operating in open or semi-public RF environments for early patching.
