…ate and protocol opens Why this is a real bug: After allocating Private via AllocateZeroPool (line ~1201) and successfully opening both gEfiDevicePathProtocolGuid and gEfiPciIoProtocolGuid BY_DRIVER, the function attempts PciIo->Attributes(EfiPciIoAttributeOperationGet, ...). If this call fails, the code executes return Status instead of goto Exit. Trigger path: NvmExpressDriverBindingStart is called. OpenProtocol for DevicePath succeeds (opens BY_DRIVER). OpenProtocol for PciIo succeeds (opens BY_DRIVER). AllocateZeroPool for Private succeeds. PciIo->Attributes(Get) returns an error. return Status bypasses the Exit: label. Why this is NOT a false positive: The Exit: label at line ~1340 performs FreePool(Private), gBS->CloseProtocol(PciIo), and gBS->CloseProtocol(DevicePath). The direct return skips all of these. No other caller cleans up Private or closes the protocols. Consequence: Memory leak of NVME_CONTROLLER_PRIVATE_DATA. Two protocols remain opened BY_DRIVER on the controller handle, preventing other drivers from binding.
