What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
