  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Drain RCU callbacks during module teardown\n\ndevx_free_subscription() can remain queued after the last DevX event file\ndrops its module reference or an auxiliary driver detaches its devices.\nmlx5_ib can then unload before the callback runs.\n\nRegistration error unwind has the same risk because driver registration\ncan attach existing devices before failing. Wait after all drivers have\nstopped.",
