CVE-2026-20890: Escalation of Privilege in Intel(R) PROSet/Wireless WiFi Software for Windows
Improper privilege management for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Privileged Process may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a high complexity attack may enable escalation of privilege. 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 (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability in Intel(R) PROSet/Wireless WiFi Software for Windows arises from improper privilege management in a privileged process running at Ring 2. An unauthenticated, unprivileged local adversary with high attack complexity could exploit this flaw to escalate privileges on the affected system. The vulnerability affects confidentiality, integrity, and availability, with availability impact rated high. No specific affected versions or patches are provided in the available data. No known exploits are reported in the wild.
Potential Impact
The vulnerability may allow an unprivileged local attacker to escalate privileges, potentially impacting system confidentiality and integrity at a low level, and availability at a high level. This could lead to denial of service or other disruptions affecting system availability. No direct evidence of exploitation or broader impact is reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation is provided in the available data. Users should monitor Intel's advisories for updates and apply any released patches promptly.
