CVE-2026-20727: 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 0: Kernel may allow a denial of service. Unprivileged software 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.
AI Analysis
Technical Summary
This vulnerability involves a null pointer dereference within the Ring 0 kernel component of Intel(R) PROSet/Wireless WiFi Software for Windows. It allows an unauthenticated, unprivileged attacker with adjacent access to cause a denial of service, resulting in system unavailability. The attack requires no user interaction and is considered low complexity. The CVSS 4.0 base score is 8.3, reflecting high impact on availability and no impact on confidentiality or integrity. No vendor remediation level or patch information is provided in the available data.
Potential Impact
The vulnerability can cause a denial of service condition on affected systems, impacting availability. There is no impact on confidentiality or integrity. The attack can be performed without privileges or user interaction, but requires adjacent access to the vulnerable system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation is currently documented. Monitor Intel's advisories for updates.
