Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A reference count leak exists in the Linux kernel’s hardware random number generator (hwrng) AMD driver. The issue stems from the
for each pci dev() loop, implemented by pci get device(), which does not always decrease the reference count for PCI devices when the loop is exited prematurely with a non-NULL pdev. Specifically, the missing pci dev put() call on both normal and error paths leads to a PCI device reference count leak.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
