  "description": "In the Linux kernel, the following vulnerability has been resolved:  tracing: Fix memory leak in test_gen_synth_cmd() and test_empty_synth_event()  test_gen_synth_cmd() only free buf in fail path, hence buf will leak when there is no failure. Add kfree(buf) to prevent the memleak.
