Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ACPI: driver: Check ACPI_COMPANION() against NULL during probe<br />
<br />
Since every platform driver can be forced to match a device that doesn&#39;t<br />
match its list of device IDs because of device_match_driver_override(),<br />
platform drivers that rely on the existence of a device&#39;s ACPI companion<br />
object should verify its presence.<br />
<br />
Accordingly, add requisite ACPI_COMPANION() or ACPI_HANDLE() checks<br />
against NULL to 13 platform drivers handling core ACPI devices.<br />
<br />
Also change the value returned by the ACPI thermal zone driver when<br />
the device&#39;s ACPI companion is not present to -ENODEV for consistency<br />
with the other drivers.
