Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ocxl: fix pci device refcount leak when calling get_function_0()<br /> <br /> get_function_0() calls pci_get_domain_bus_and_slot(), as comment<br /> says, it returns a pci device with refcount increment, so after<br /> using it, pci_dev_put() needs be called.<br /> <br /> Get the device reference when get_function_0() is not called, so<br /> pci_dev_put() can be called in the error path and callers<br /> unconditionally. And add comment above get_dvsec_vendor0() to tell<br /> callers to call pci_dev_put().
