Key facts

Description

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: fix possible memory leak in ibmebus_bus_init() If device_register() returns error in ibmebus_bus_init(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked. As comment of device_add() says, it should call put_device() to drop the reference count that was set in device_initialize() when it fails, so the name can be freed in kobject_cleanup().
