Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/radeon: Fix PCI device refcount leak in radeon_atrm_get_bios()<br /> <br /> As comment of pci_get_class() says, it returns a pci_device with its<br /> refcount increased and decreased the refcount for the input parameter<br /> @from if it is not NULL.<br /> <br /> If we break the loop in radeon_atrm_get_bios() with &amp;#39;pdev&amp;#39; not NULL, we<br /> need to call pci_dev_put() to decrease the refcount. Add the missing<br /> pci_dev_put() to avoid refcount leak.
