In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Balance device refcount when destroying devices Using device_find_child() to lookup the proper SCMI device to destroy causes an unbalance in device refcount, since device_find_child() calls an implicit get_device(): this, in turns, inhibits the call of the provided release methods upon devices destruction. As a consequence, one of the structures that is not freed properly upon destruction is the internal struct device_private dev->p populated by the drivers subsystem core. KMemleak detects this situation si
