CVE-2026-20776 Intel CVE debrief

Who should care

Network administrators, Intel(R) PROSet/Wireless WiFi Software users, cybersecurity teams, and vulnerability management teams should be aware of the potential vulnerability and take necessary actions to verify and mitigate the risk. Affected operators and platforms may be impacted, and security teams should review and implement compensating controls. 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. Evidence is limited to public CVE and NVD records, and further verification is required to confirm affected scope and severity. Official CVE and NVD records detail potential improper conditions check vulnerability in Intel(R) PROSet/Wireless WiFi Software; verify affected versions and apply patches. The vulnerability may impact network availability, and defenders should assess adjacent access and system exposure. Evidence is limited to public CVE and NVD records, and further verification is required to confirm affected scope and severity. Network administrators should review network exposure and apply patches. Cybersecurity teams should implement compensating controls for network security. Vulnerability management teams should verify system configurations and user interactions. Intel(R) PROSet/Wireless WiFi Software users should monitor network for unusual activity and restrict adjacent access to vulnerable systems.

Technical summary

The vulnerability is caused by an improper conditions check in Intel(R) PROSet/Wireless WiFi Software within Ring 2: Device Drivers. This may allow denial of service via adjacent access; assess network exposure and apply patches. The vulnerability has a high impact on availability and may be exploited by a network adversary with an unauthenticated user and low complexity attack. Network service disruption via adjacent access may occur; verify and apply vendor remediation.

Defensive priority

Network service disruption via adjacent access may occur; verify and apply vendor remediation.

Recommended defensive actions

• Inventory affected Intel(R) PROSet/Wireless WiFi Software versions
• Apply vendor patches or updates
• Monitor network for unusual activity
• Restrict adjacent access to vulnerable systems
• Implement compensating controls for network security
• Review network exposure and apply patches
• Verify system configurations and user interactions
