Summary

In the Linux kernel, the bcmgenet driver has a flawed timeout handler: it stops all transmit queues when a single queue times out, causing race conditions with queues that are still functioning. The fix restarts only the timed-out queue.

Risk Assessment

The organization may experience network instability, packet loss, or network interface hangs on systems using the bcmgenet driver.

Recommendation

Update the Linux kernel to a version containing the fix for this vulnerability (the commit that resolves the issue).

Original NVD description (English source)

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.
