CVE-2021-47424

The CVE-2021-47424 issue affects the Linux kernel i40e driver. When VSI setup fails during PF switch in i40e_probe(), the code attempted to free misc IRQ vectors in i40e_clear_interrupt_scheme, potentially freeing an IRQ that had not been allocated yet, leading to a kernel Oops (example trace sho...
