Lifecycle Timeline
2DescriptionCVE.org
Out-of-bounds write 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 (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.
AnalysisAI
Out-of-bounds write in Intel PROSet/Wireless WiFi Software for Windows device drivers (Ring 2) allows adjacent network attackers to trigger a denial of service condition without authentication or user interaction. Unauthenticated attackers on the same network segment can exploit this CWE-787 buffer overflow flaw with low complexity, causing high availability impact to the affected Windows system and low residual availability impact on subsequent systems. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker must have adjacent network access - physically co-located on the same WiFi network segment, same wired LAN broadcast domain, or adjacent network infrastructure (e.g., same VLAN, same wireless access point). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 is primarily driven by the adjacent attack vector (AV:A), which materially constrains real-world exploitation - attackers must be physically co-located on the same wireless LAN, VLAN, or wired adjacent network segment. … 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 apply the patch referenced in Intel Security Advisory INTEL-SA-01422 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html - consult that advisory for the exact fixed driver version, as no specific patch version number was included in the available input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
