Summary

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

net/mlx5e: Check for NOT_READY flag state after locking

Currently the check for NOT_READY flag is performed before obtaining the necessary lock. This opens a possibility for race condition when the flow is concurrently removed from unready_flows list by the workqueue task, which causes a double-removal from the list and a crash[0]. Fix the issue by moving the flag check inside the section protected by uplink_priv->unready_flows_lock mutex.
