Security readout for executives and security teams
CVE-2015-2291 affects Intel’s Windows Ethernet diagnostics driver files IQVW32.sys and IQVW64.sys before version 1.3.1.0. A local user can abuse faulty input handling to crash the system or potentially run code with kernel privileges. Because CISA lists it in KEV, treat it as exploited in the wild. Exposure is limited to Windows systems where Intel Ethernet diagnostics driver IQVW32.sys or IQVW64.sys is installed below version 1.3.1.0. The source bundle does not identify broader affected product packages or CPEs, so asset discovery should verify driver presence and version directly. High priority. This is an older local driver flaw, but KEV status means real-world exploitation is supported by CISA. Remediate quickly on Windows fleets because successful abuse can move an attacker from user-level access to kernel-level control or cause outages. Mitigation focus: Find Windows hosts with IQVW32.sys or IQVW64.sys installed.; Update vulnerable Intel diagnostics drivers to version 1.3.1.0 or later where applicable.; Remove the diagnostics driver if it is not operationally required..

Improper Input Validation
Improper Input Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
