Summary
In the Linux kernel, the following vulnerability has been resolved:
power: supply: fix null pointer dereferencing in power_supply_get_battery_info
when kmalloc() fail to allocate memory in kasprintf(), propname
will be NULL, strcmp() called by of_get_property() will cause
null pointer dereference.
So return ENOMEM if kasprintf() return NULL pointer.
