CVE-2024-27014 is a deadlock vulnerability in the Linux kernel mlx5e networking driver when disabling accelerated Receive Flow Steering (aRFS). The disable operation holds priv->state_lock while calling cancel_work_sync to cancel aRFS work. If an aRFS worker has already started, cancellation waits for that worker to finish, but the worker attempts to acquire the same state lock to delete rules when the interface state is down. This circular dependency can deadlock the disable operation and worker. The affected path includes mlx5e_arfs_disable and arfs_handle_work and can be reached during channel reconfiguration through mlx5e_ethtool_set_channels.
