Lifecycle Timeline
2DescriptionCVE.org
Exposure of sensitive information to an unauthorized actor 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.
AnalysisAI
Local privilege escalation and code execution in Intel PROSet/Wireless WiFi Software for Windows arises from an information disclosure flaw (CWE-200) within the Ring 2 device driver layer, exploitable by an unprivileged local user without authentication or user interaction. The vulnerable system itself suffers only low confidentiality impact, but a scope change into the driver subsystem produces high subsequent-system confidentiality impact alongside low integrity and availability impacts - consistent with a privilege escalation chain from user space into driver-controlled memory. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to a Windows system with Intel PROSet/Wireless WiFi Software installed and active. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.3 reflects a moderate-priority finding with a local attack vector (AV:L), which meaningfully limits the attack surface compared to network-reachable vulnerabilities. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to consult Intel Security Advisory INTEL-SA-01422 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html and apply the patched driver version identified therein - an exact fix version was not independently confirmable from the available data and must be sourced directly from the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
