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

powercap: intel rapl: Fix memory leak in rapl add package cpuslocked()

When topology physical package id()/topology logical die id() returns a negative value, rapl add package cpuslocked() returns ERR PTR(-EINVAL) directly without freeing the rapl package structure that was just allocated by kzalloc obj(), leaking memory on every failed package addition.

Use the existing err free package label so that the allocation is released on the error path.
