In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix queues reservation for XDP
When XDP was configured on a system with large number of CPUs and X722 NIC there was a call trace with NULL pointer dereference.
i40e 0000:87:00.0: failed to get tracking for 256 queues for VSI 0 err -12 i40e 0000:87:00.0: setup of MAIN VSI failed

This was caused by PF queue pile fragmentation due to flow director VSI queue being placed right after main VSI. Because of this main VSI was not able to resize its queue allocation for XDP resulting in no queues allocated for main VSI when XDP was turned on.
Fix this by always allocating last queue in PF queue pile for a flow director VSI.
