Lifecycle Timeline
2DescriptionCVE.org
Null pointer dereference for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 0: Kernel may allow a denial of service. Unprivileged software 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
Intel PROSet/Wireless WiFi Software for Windows contains a null pointer dereference in Ring 0 (kernel space) that an adjacent, unauthenticated attacker can exploit to crash the target system, resulting in a denial of service. The flaw resides in the WiFi kernel driver, meaning a successful trigger causes a kernel panic (BSOD on Windows) with high availability impact on both the vulnerable component and the broader system. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same adjacent network segment (Layer 2 adjacency) as the target - for example, connected to the same WiFi access point or within wireless range on an open or shared SSID. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 8.3 accurately reflects the combination of no-auth, no-user-interaction, and high availability impact, but the AV:A (adjacent network) constraint is the critical limiter - exploitation requires the attacker to share a Layer 2 network segment (e.g., the same WiFi access point or broadcast domain) with the target. … 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 driver package referenced in Intel Security Advisory INTEL-SA-01468 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01468.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
