Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ACPI: NFIT: core: Fix possible NULL pointer dereference<br />
<br />
After commit 9b311b7313d6 ("ACPI: NFIT: Install Notify() handler before<br />
getting NFIT table"), acpi_nfit_probe() installs an ACPI notify handler<br />
for the NFIT device before checking the presence of the NFIT table. If<br />
that table is not there, 0 is returned without allocating the acpi_desc<br />
object and setting the driver data pointer of the NFIT device. If the<br />
platform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification<br />
on the NFIT device at that point, acpi_nfit_uc_error_notify() will<br />
dereference a NULL pointer.<br />
<br />
Prevent that from occurring by adding an acpi_desc check against NULL<br />
to acpi_nfit_uc_error_notify().
