Lifecycle Timeline
2DescriptionCVE.org
Null pointer dereference 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 (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.
AnalysisAI
Null pointer dereference in Intel PROSet/Wireless WiFi Software for Windows at the Ring 2 device driver layer enables denial of service by an unauthenticated adjacent-network attacker. Disclosed by Intel in advisory INTEL-SA-01422, the flaw affects all currently indexed versions of the software and can be triggered at low complexity with no user interaction or special attack prerequisites. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same adjacent network as the target - same SSID, VLAN, or broadcast domain - as confirmed by AV:A in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 with base vector AV:A/AC:L/AT:N/PR:N/UI:N reflects an adjacent-network unauthenticated DoS - meaningful but structurally bounded by the adjacency requirement. … 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 | Consult Intel Security Advisory INTEL-SA-01422 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html) for the exact patched driver version and download instructions, as NVD CPE data does not specify a fixed version independently. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Conduct an inventory of all systems running Intel PROSet/Wireless WiFi Software using endpoint management tools to quantify exposure scope. …
