Technical details

An improper access control vulnerability exists in the Ring 2 (kernel-mode) device drivers of Intel PROSet/Wireless WiFi Software for Windows. The vulnerability allows unprivileged local software to execute code with kernel-level privileges without prior authentication or user interaction, exploiting a low-complexity attack path. An attacker can achieve local code execution with high impact to system confidentiality and availability. Intel has released software updates to mitigate these vulnerabilities; systems should be updated to the latest patched version.
