Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
IB/IPoIB: Fix legacy IPoIB due to wrong number of queues
The cited commit creates child PKEY interfaces over netlink will multiple tx and rx queues, but some devices doesn't support more than 1 tx and 1 rx queues. This causes to a crash when traffic is sent over the PKEY interface due to the parent having a single queue but the child having multiple queues.
This patch fixes the number of queues to 1 for legacy IPoIB at the earliest possible point in time.
