Title
ACPI: NFIT: core: Fix possible NULL pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: NFIT: core: Fix possible NULL pointer dereference
After commit 9b311b7313d6 ("ACPI: NFIT: Install Notify() handler before
getting NFIT table"), acpi_nfit_probe() installs an ACPI notify handler
for the NFIT device before checking the presence of the NFIT table. If
that table is not there, 0 is returned without allocating the acpi_desc
object and setting the driver data pointer of the NFIT device. If the
platform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification
on the NFIT device at that point, acpi_nfit_uc_error_notify() will
dereference a NULL pointer.
Prevent that from occurring by adding an acpi_desc check against NULL
to acpi_nfit_uc_error_notify().
Severity
No CVSS data available.
