hwmon: (asus_atk0110) Check package count before accessing element
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.
