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 (high) impacts.
AnalysisAI
Denial of service in Intel PROSet/Wireless WiFi Software affects the Ring 2 device driver layer, where an improper conditions check (CWE-754) can be triggered by an adjacent, unauthenticated attacker with no user interaction required. The vulnerability collapses wireless availability on the affected host and, per the CVSS 4.0 vector, cascades to subsequent system availability as well, meaning dependent network-connected services may also be disrupted. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be physically or logically adjacent to the target - on the same broadcast domain, Wi-Fi segment, or within wireless range - which is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.3 with AV:A/AC:L/AT:N/PR:N/UI:N reflects a meaningful but physically constrained threat: an unauthenticated attacker must be within adjacent network range (same Wi-Fi segment or physical proximity), lowering mass-internet exploitation risk. … 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 the Intel security advisory INTEL-SA-01422 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01422.html) for the vendor-confirmed patched version - an exact fix version is not independently confirmed from the available input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
