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.

</TASK>
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: IB/IPoIB: corrige el IPoIB heredado debido a un número incorrecto de colas. La confirmación citada crea interfaces PKEY secundarias a través de netlink y tendrá múltiples colas de transmisión y recepción, pero algunos dispositivos no admiten más de Colas 1 tx y 1 rx. Esto provoca un bloqueo cuando el tráfico se envía a través de la interfaz PKEY debido a que el padre tiene una sola cola pero el hijo tiene varias colas. Este parche fija el número de colas en 1 para IPoIB heredado lo antes posible.
