Lifecycle Timeline
2DescriptionCVE.org
Improper conditions check for some Intel(R) PROSet/Wireless WiFi Software 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 (none) impacts.
AnalysisAI
Denial of service in Intel PROSet/Wireless WiFi Software device drivers (Ring 2) allows an unauthenticated adjacent-network attacker to crash or disable the wireless subsystem on affected systems. The flaw stems from an improper conditions check (CWE-754) within the WiFi driver stack, meaning edge-case or malformed network input is not handled safely, leading to complete availability loss of the vulnerable system. …

Vulnerability AssessmentAI
| Exploitation | Attacker must have adjacent network access - specifically, be within WiFi radio range or on the same network segment as the target device running Intel PROSet/Wireless WiFi Software. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 is driven by AV:A (adjacent network), AC:L (low complexity), PR:N (no privileges), UI:N (no user interaction), and VA:H (high availability impact). … 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 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html to obtain the patched version of Intel PROSet/Wireless WiFi Software for the affected hardware. … Detailed patch versions, workarounds, and compensating controls in full report. |
