**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue arises when the VSI setup fails in `i40e probe()` as part of PF switch setup, causing the driver to attempt to free misc IRQ vectors in `i40e clear interrupt scheme()`. This results in a kernel Oops due to trying to free already-free IRQ vectors. The problem occurs because misc IRQ vectors were not allocated at that point. A check has been added in `i40e clear interrupt scheme()` for the ` I40E MISC IRQ REQUESTED` PF state before calling `i40e free misc vector()`, which is set only if misc IRQ vectors were properly initialized. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
