CVE-2022-50868

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hwrng: amd - Fix PCI device refcount leak<br /> <br /> for_each_pci_dev() is implemented by pci_get_device(). The comment of<br /> pci_get_device() says that it will increase the reference count for the<br /> returned pci_dev and also decrease the reference count for the input<br /> pci_dev @from if it is not NULL.<br /> <br /> If we break for_each_pci_dev() loop with pdev not NULL, we need to call<br /> pci_dev_put() to decrease the reference count. Add the missing<br /> pci_dev_put() for the normal and error path.
