Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue related to a PCI device reference count leak within the
ppr notifier() function in the iommu/amd module. The pci get domain bus and slot() function increments the reference count of a PCI device. To prevent a reference count leak, the caller must decrement this reference count by calling pci dev put() before returning from ppr notifier(). This issue could potentially lead to resource exhaustion or other unexpected behavior.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
