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

net/mlx5: Lag, fix failure to cancel delayed bond work

Commit 0d4e8ed139d8 ("net/mlx5: Lag, avoid lockdep warnings") accidentally removed a call to cancel delayed bond work thus it may cause queued delay to expire and fall on an already destroyed work queue.

Fix by restoring the call cancel_delayed_work_sync() before destroying the workqueue.

This prevents call trace such as this:
