CVE-2026-20741 - Vulnerability Details

- Denial of Service via Improper Access Control in Intel PROSet/Wireless WiFi Software

Description

Improper access control for some Intel(R) PROSet/Wireless WiFi Software 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 (low) and availability (high) impacts.

Analysis

Impact

A flaw in the device drivers of Intel PROSet/Wireless WiFi Software allows an attacker with unprivileged local code to exploit improper access control at Ring 2, causing a denial of service. The vulnerability requires no user interaction and does not disclose or modify data, so confidentiality and integrity are not impacted; only availability is affected.

Affected Systems

Intel PROSet/Wireless WiFi Software. All installations of this Intel software are potentially impacted until a vendor patch is released, as no specific vulnerable version is identified in the advisory.

Risk and Exploitability

The CVSS score of 8.3 indicates high severity, while the EPSS score of less than 1 % shows a low probability of exploitation. The vulnerability is not listed in CISA’s KEV catalog. Attackers need local access and only unprivileged code; no special internal knowledge or user interaction is required.

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

Apply any patch or update released by Intel that addresses this issue, as documented in the Intel Security Advisory.
If a patch is not available, consider disabling or uninstalling the Intel PROSet/Wireless WiFi Software to remove the vulnerable driver.
Limit local access rights for unprivileged users, enforce least‑privilege practices, and monitor system logs for repeated denial‑of‑service events.
Consider using network segmentation or disabling Wi‑Fi hardware when the software is not needed to reduce exposure.
