CVE-2026-20787: Denial of Service in Intel(R) PROSet/Wireless WiFi Software for Windows
Null pointer dereference 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.
AI Analysis
Technical Summary
This vulnerability involves a null pointer dereference within the Ring 2 device drivers of Intel(R) PROSet/Wireless WiFi Software for Windows. Exploitation requires an attacker to have adjacent network access but no authentication or user interaction is needed. The attack complexity is low, and the vulnerability results in a denial of service condition affecting system availability. There is no impact on confidentiality or integrity. The CVSS 4.0 base score is 7.1, reflecting high severity due to availability impact. No vendor advisory or patch information is provided at this time.
Potential Impact
The vulnerability allows a network adversary with adjacent access to cause a denial of service on affected systems, impacting availability. There is no impact on confidentiality or integrity. The denial of service may disrupt normal operation of the wireless software and potentially the system's network connectivity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is available at this time.
