CVE-2026-20780: Denial of Service in Intel(R) PROSet/Wireless WiFi Software for Windows
Uncontrolled resource consumption for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers 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 local 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 in Intel(R) PROSet/Wireless WiFi Software for Windows allows an unauthenticated, unprivileged local attacker to cause uncontrolled resource consumption in device drivers operating at Ring 2, leading to denial of service. The attack requires no user interaction and has low complexity. The vulnerability does not impact confidentiality or integrity but results in high impact on availability of the affected system. No patch or remediation level is currently specified, and no known exploits are reported in the wild.
Potential Impact
The vulnerability results in denial of service by exhausting system resources, impacting the availability of the affected system. There is no impact on confidentiality or integrity. The availability impact is rated high at the vulnerability level but results in a low subsequent availability impact on system confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been reported at this time.
