CVE-2026-20778: Denial of Service in Intel(R) PROSet/Wireless WiFi Software for Windows
Out-of-bounds read 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 high complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are 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 is an out-of-bounds read in Intel(R) PROSet/Wireless WiFi Software for Windows operating in kernel mode (Ring 0). An unauthenticated attacker with no privileges can cause a denial of service by triggering this flaw, although the attack complexity is high. The vulnerability does not compromise confidentiality or integrity but can severely impact system availability. The CVSS 4.0 score is 7.0, reflecting high severity. No vendor advisory or patch information is available at this time.
Potential Impact
The vulnerability can cause denial of service (availability impact) on affected systems running Intel(R) PROSet/Wireless WiFi Software for Windows. There is no impact on confidentiality or integrity. The attack requires adjacent access and has high complexity, with no privileges or user interaction needed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is currently available.
