Description

In the Linux kernel, the following vulnerability has been resolved: tracing: Don't dereference trace_event_file in deferred trigger free The enable_event trigger defers trace_event_put_ref() to the trigger free kthread, but the trace_event_file can already be freed when the instance is removed. Keep the trace_event_call directly in enable_trigger_data so the deferred free does not access the freed trace_event_file.
