Details

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix PCI device refcount leak in dmardevscopeinit() foreachpcidev() is implemented by pcigetdevice(). The comment of pcigetdevice() says that it will increase the reference count for the returned pcidev and also decrease the reference count for the input pcidev @from if it is not NULL. If we break foreachpcidev() loop with pdev not NULL, we need to call pcidevput() to decrease the reference count. Add the missing pcidev_put() for the error path to avoid reference count leak.
