Description

In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Avoid use of NULL after WARN_ON_ONCE

There is a WARN_ON_ONCE to catch an unlikely situation when
domain_remove_dev_pasid can't find the `pasid`. In case it nevertheless
happens we must avoid using a NULL pointer.
