- Summary
- xen/netback: avoid entering xenvif_rx_next_skb() with an empty rx queue
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
xen/netback: avoid entering xenvifrxnext_skb() with an empty rx queue
xenvifrxnextskb() is expecting the rx queue not being empty, but in case the loop in xenvifrx_action() is doing multiple iterations, the availability of another skb in the rx queue is not being checked.
This can lead to crashes:

Fix that by stopping the loop in case the rx queue becomes empty.
