Summary
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).
