In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix mlx5e_priv_init() cleanup flow
When mlx5e_priv_init() fails, the cleanup flow calls mlx5e_selq_cleanup which calls mlx5e_selq_apply() that assures that the `priv->state_lock` is held using lockdep_is_held().
Acquire the state_lock in mlx5e_selq_cleanup().
Kernel log: ============================= WARNING: suspicious RCU usage 6.8.0-rc3_net_next_841a9b5 #1 Not tainted ----------------------------- drivers/net/ethernet/mellanox/mlx5/core/en/selq.c:124 suspicious rcu_dereference_protected() usage!
