Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: bcmgenet: fix racing timeout handler<br /> <br /> The bcmgenet_timeout handler tries to take down all tx queues when<br /> a single queue times out. This is over zealous and causes many race<br /> conditions with queues that are still chugging along. Instead lets<br /> only restart the timed out queue.
