  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Have show_event_filters/triggers files take trace array ref\n\nThe newly added files show_event_filters and show_event_triggers that show\nall filters or triggers that are set within the trace array do not take a\nreference for the trace array it is showing. Without taking a reference,\nthe trace_array may be freed via \"rmdir\" while a task is reading one of\ntheses files. Those files iterate all the events within an instance\n(trace_array) and nothing prevents that instance from being freed while\nits data is being read. This causes a use-after-free crash.\n\nHave the open of both those files take the trace_array reference via the\ntrace_array_get() that prevents the trace_array from being freed while the\nfiles are opened.",
