Answer in brief
CVE-2026-20891 records a Medium severity (CVSS 6.3) vulnerability in CISA ADP Vulnrichment. The current sources do not mark it as known exploited. The current feed maps n/a/Intel(R) PROSet/Wireless WiFi Software for Windows (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Improper authentication for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable local code execution. 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 (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (low) and availability (low) impacts.
