Description
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).

• linux linux kernel (>= 5.11 < 5.15.19)
