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