Detailsinfo

A vulnerability, which was classified as problematic, has been found in Intel Ethernet Adapter Complete Driver Pack Software. Affected by this issue is an unknown function. The manipulation with an unknown input leads to a toctou vulnerability. Using CWE to declare the problem leads to CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. Impacted is availability. CVE summarizes:

Time-of-check time-of-use race condition for some Intel Ethernet Adapter Complete Driver Pack software before version 1.5.1.0 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated 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 active 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 (none) impacts.

The advisory is shared for download at intel.com. This vulnerability is handled as CVE-2025-31146 since 04/15/2025. The exploitation is known to be easy. The attack needs to approached within the local network. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.

Upgrading to version 1.5.1.0 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2025-2550). Once again VulDB remains the best source for vulnerability data.
