A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

net: bcmgenet: fix racing timeout handler

The bcmgenet_timeout handler tries to take down all tx queues when a single queue times out. This is over zealous and causes many race conditions with queues that are still chugging along. Instead lets only restart the timed out queue.
