  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/ipoib: Drain RCU callbacks during module teardown\n\nIPoIB reclamation completions can be signaled from inside an RCU callback.\nTeardown can wake before the callback returns and unload ib_ipoib while its\ncode is still executing.\n\nClient registration failure can also remove already-added devices and queue\ncallbacks. Wait after client and workqueue teardown.",
