A stack‑based buffer overflow exists in the kernel mode component of Intel PROSet / Wireless WiFi Software for Windows. The flaw allows an attacker to corrupt the stack of the operating‑system kernel, leading to a crash of the system and a denial of service. The vulnerability does not expose confidentiality or integrity weaknesses, but it can render the affected machine unusable. The weakness is categorized as CWE‑121, a classic stack overflow.

The affected product is Intel PROSet / Wireless WiFi Software for Windows. No specific affected version numbers are supplied in the advisory. System owners should verify the version of the Intel wireless driver installed on each Windows machine.

The CVSS score of 8.3 indicates a high‑severity flaw, but the EPSS score of < 1% shows that the probability of widespread exploitation is very low at present. The attack does not require special internal knowledge, no user interaction, and can be performed by any unprivileged process. The sole impact is loss of availability of the system. The vulnerability is not listed in the CISA KEV catalog, and no official workaround is currently provided. The likely attack vector is local kernel exploitation via adjacent memory access that triggers the overflow. The combination of low complexity and no interaction makes the flaw approachable for malicious actors with basic local access to the target machine.
