  "summary": "fbdev: uvesafb: unregister connector callback on init failure",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: uvesafb: unregister connector callback on init failure\n\nuvesafb_init() registers the v86d connector callback before registering\nthe platform driver. If platform_driver_register() fails, the function\nreturns the error directly and leaves the connector callback registered.\n\nThe later platform-device failure path already unregisters the callback.\nAdd the same cleanup before the final return when platform-driver\nregistration fails.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.",
