CVE-2026-20878: 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 in Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2 device drivers. An unauthenticated network attacker with adjacent access and low attack complexity may cause a denial of service condition. The attack does not require user interaction or special privileges and does not affect confidentiality or integrity, only availability. The CVSS 4.0 base score is 7.1, indicating high severity. No vendor advisory or patch information is provided at this time.
Potential Impact
The vulnerability allows an unauthenticated adjacent network attacker to cause a denial of service by triggering a null pointer dereference in the affected device drivers. This results in high impact on system availability but no impact on confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation has been documented at this time.
