In the Linux kernel, the following vulnerability has been resolved:

fbdev: uvesafb: unregister connector callback on init failure

uvesafb_init() registers the v86d connector callback before registering

the platform driver. If platform_driver_register() fails, the function

returns the error directly and leaves the connector callback registered.

The later platform-device failure path already unregisters the callback.

Add the same cleanup before the final return when platform-driver

registration fails.

This issue was identified during our ongoing static-analysis research while

reviewing kernel code. (NVD)
