CVE-2025-39911

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

A flaw was found in the Linux kernel’s i40e network driver (function i40e_vsi_request_irq_msix()). If request_irq() fails on a later iteration than the first, the error-path tries to call free_irq() for previously requested IRQs but passes an incorrect dev_id. As a result, some IRQs are not properly freed and the driver may trigger kernel warnings or resource cleanup inconsistencies.
