A fix is available — apply it.

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

EDAC/versalnet: Fix device name memory leak

The device name allocated via kzalloc() in init_one_mc() is assigned to dev->init_name but never freed on the normal removal path. device_register() copies init_name and then sets dev->init_name to NULL, so the name pointer becomes unreachable from the device. Thus leaking memory.

Use a stack-local char array instead of using kzalloc() for name.
