Description

In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]hwrng: geode - Fix PCI device refcount leak[EOL][EOL]for_each_pci_dev() is implemented by pci_get_device(). The comment of[EOL]pci_get_device() says that it will increase the reference count for the[EOL]returned pci_dev and also decrease the reference count for the input[EOL]pci_dev @from if it is not NULL.[EOL][EOL]If we break for_each_pci_dev() loop with pdev not NULL, we need to call[EOL]pci_dev_put() to decrease the reference count. We add a new struct[EOL]'amd_geode_priv' to record pointer of the pci_dev and membase, and then[EOL]add missing pci_dev_put() for the normal and error path.
