CVE-2025-39969

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to the i40e network driver. The issue involves incorrect validation of Virtual Function (VF) state when obtaining resources. Specifically, the I40E VF STATE ACTIVE state was being used to determine if a VF was permitted to acquire resources, which is inaccurate as this state doesn't exclusively indicate an active VF. The correction involves utilizing I40E VF STATE RESOURCES LOADED, which is set only during resource allocation and cleared upon reset, to accurately assess VF resource access permissions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
