  "title": "ixgbe: do not configure xps for XDP queues",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ixgbe: do not configure xps for XDP queues  netif_set_xps_queue() should not be called for an XDP Tx queue, since such queues are not netdev-exposed. On systems with number of CPUs \u003E=64, on E610 adapter, netdev is configured with maximum number queue pairs being 63 (due to MSI-X assignment), but configuring XDP results in 64 XDP queues.  So, during XDP program load, when netif_set_xps_queue() is called for the last XDP queue, we get a WARNING with a call trace and KASAN report afterwards (if enabled).
