## Description

In the Linux kernel, the following vulnerability has been resolved:  hwmon: (asus_atk0110) Check package count before accessing element  atk_ec_present() walks the management group package returned by the GGRP ACPI method and, for each sub-package, reads its first element:  	id = &obj->package.elements[0]; 	if (id->type != ACPI_TYPE_INTEGER)  without checking that the sub-package is non-empty.  ACPICA allocates the element array with exactly package.count entries, so for a sub-package with a zero count this reads past the allocation.  The sibling function atk_debugfs_ggrp_open() performs the same access but skips empty packages with a package.count check first.  Add the same check to atk_ec_present() so a malformed firmware package cannot trigger an out-of-bounds read.
