Details

In the Linux kernel, the following vulnerability has been resolved: drm/xe/nvm: Fix double-free on aux add failure After a successful auxiliarydeviceinit(), auxdev->dev.release (xenvmreleasedev()) is responsible for the kfree(nvm). When there is failure with auxiliarydeviceadd(), driver will call auxiliarydeviceuninit(), which call putdevice(). So that the .release callback will be triggered to free the memory associated with the auxiliarydevice. Move the kfree(nvm) into the auxiliarydeviceinit() failure path and remove the err goto path to fix below error.
