  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Delay module ref count for \"enable_event\" trigger\n\nTriggers are now delayed from freeing, but can still be triggered until\nafter the RCU grace period has ended. The freeing of the enable_event data\nis put into the private_data_free() callback, but the put of the module\nrefcount is done immediately.\n\nIt is possible that if a module is removed that has an event that would\nenable (or disable) it is still active, it can read the data of the module\nafter it is removed causing a use-after-free bug.\n\nMove the trace_event_put_ref() that releases the module into the delayed\ncallback so that the module can not be removed until any reference to its\nevents are finished.",
