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
Denial of service in Intel PROSet/Wireless WiFi Software for Windows stems from a null pointer dereference (CWE-476) in the Ring 2 device driver layer, allowing an adjacent unauthenticated attacker to crash the affected system with no user interaction required. The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VA:H) confirms low-complexity exploitation from the same network segment, resulting in high availability impact to the vulnerable system and residual low availability impact to subsequent systems. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same network segment as the target - the same WiFi network, VLAN, or LAN - satisfying the adjacent access requirement (AV:A). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 with AV:A/AC:L/AT:N/PR:N/UI:N reflects a credible denial-of-service threat constrained to adjacent network access, with high availability impact on the vulnerable system and low residual availability impact on subsequent systems (SA:L), suggesting driver crashes may propagate to broader system instability. … 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 updated Intel PROSet/Wireless WiFi Software for Windows as specified in Intel Security Advisory INTEL-SA-01422, available at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory Windows systems running Intel PROSet/Wireless WiFi Software and assess their exposure to untrusted adjacent networks (guest WiFi, shared facilities, open networks). …
