CVE-2024-27014

Estado: ModificadaMedia (5.5)—

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

net/mlx5e: Prevent deadlock while disabling aRFS

When disabling aRFS under the `priv->state_lock`, any scheduled aRFS works are canceled using the `cancel_work_sync` function, which waits for the work to end if it has already started. However, while waiting for the work handler, the handler will try to acquire the `state_lock` which is already acquired.

The worker acquires the lock to delete the rules if the state is down, which is not the worker's responsibility since disabling aRFS deletes the rules.

Add an aRFS state variable, which indicates whether the aRFS is enabled and prevent adding rules when the aRFS is disabled.

Sin embargo, mientras espera el controlador de trabajo, el controlador intentará adquirir el `state_lock` que ya está adquirido. El trabajador adquiere el bloqueo para eliminar las reglas si el estado está inactivo, lo cual no es responsabilidad del trabajador ya que al desactivar aRFS se eliminan las reglas.
