After allocating Private via AllocateZeroPool 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. Consequence: Memory leak of NVME_CONTROLLER_PRIVATE_DATA. Two protocols remain opened BY_DRIVER on the controller handle, preventing other drivers from binding. Signed-off-by: Sean Brogan <sebrogan@microsoft.com> |
