CVE-2022-50659

A reference count leak was found in the AMD Geode hardware random number generator driver in the Linux kernel. When breaking out of the for_each_pci_dev() loop early, the driver fails to call pci_dev_put() to decrement the PCI device reference count, leading to a memory leak that could exhaust system resources over time.

The AMD Geode platform is legacy hardware rarely deployed in enterprise environments. Exploitation requires local access and repeated driver operations to cause meaningful resource exhaustion.
