CVE-2024-35958

In the Linux kernel, the following vulnerability has been resolved: net:
ena: Fix incorrect descriptor free behavior ENA has two types of TX queues:

• queues which only process TX packets arriving from the network stack -
  queues which only process TX packets forwarded to it by XDP_REDIRECT or
  XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors
  in a TX queue and unmaps + frees every descriptor that hasn’t been
  acknowledged yet by the device (uncompleted TX transactions). The function
  assumes that the processed TX queue is necessarily from the first category
  listed above and ends up using napi_consume_skb() for descriptors belonging
  to an XDP specific queue. This patch solves a bug in which, in case of a VF
  reset, the descriptors aren’t freed correctly, leading to crashes.
