CVE-2026-20739 - Vulnerability Details

- Denial of Service via Improper Condition Check in Intel PROSet/Wireless WiFi Software

Description

Improper conditions check 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.

Analysis

Impact

The vulnerability results from an improper conditions check in the Intel(R) PROSet/Wireless WiFi Software for Windows drivers when executed in Ring 2. This flaw can allow an attacker to trigger a denial of service, which would stop the WiFi driver from operating and cause the system to become unavailable. No confidentiality or integrity impact is reported.

Affected Systems

Intel PROSet/Wireless WiFi Software for Windows is affected. No specific version range is listed in the data, so all current installations of this software should be evaluated for the presence of the defect.

Risk and Exploitability

The CVSS score of 7.1 indicates a medium to high severity, but the EPSS score of less than 1% suggests exploitation is unlikely at this time. The flaw is not listed in the CISA KEV catalog. An attacker would need network access, be unauthenticated, and perform a low‑complexity action to exploit the driver, typically by sending malformed Wi-Fi traffic that triggers the bad condition check.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Update Intel PROSet/Wireless WiFi Software to a version that fixes the denial‑of‑service issue; download the latest firmware or security update from Intel.
If an immediate update is not possible, disable the wireless network interface or block Wi-Fi traffic using the operating system firewall rules to prevent malicious packets from reaching the driver.
Monitor system event logs for repeated driver failures or unexpected shutdowns that may indicate an ongoing denial‑of‑service attempt.
