In the Linux kernel, the following vulnerability has been resolved:

tracing/histogram: Fix a potential memory leak for kstrdup()

kfree() is missing on an error path to free the memory allocated by
kstrdup():

  p = param = kstrdup(data->params[i], GFP_KERNEL);

So it is better to free it via kfree(p).
