Doc Text:
A flaw was found in Intel PROSet Wireless Wi-Fi Software. A heap-based buffer overflow in the kernel driver allows an unauthenticated attacker on the adjacent network to cause a Denial of Service (DoS) or compromise system integrity. By sending malicious network traffic without requiring user interaction, an attacker can trigger memory corruption, potentially resulting in an operating system crash.

Description OSIDB Bzimport 2026-11-10 19:45:56 UTC 
Heap-based buffer overflow for some Intel(R) PROSet Wireless Wi-Fi Software for Windows within Ring 0: Kernel 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 network 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 (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (high) impacts.
