      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: Fix resource leaks on errors in gpiochip_add_data_with_key()\n\nSince commit aab5c6f20023 (\"gpio: set device type for GPIO chips\"),\n`gdev->dev.release` is unset.  As a result, the reference count to\n`gdev->dev` isn't dropped on the error handling paths.\n\nDrop the reference on errors.\n\nAlso reorder the instructions to make the error handling simpler.\nNow gpiochip_add_data_with_key() roughly looks like:\n\n   >>> Some memory allocation.  Go to ERR ZONE 1 on errors.\n   >>> device_initialize().\n\n   gpiodev_release() takes over the responsibility for freeing the\n   resources of `gdev->dev`.  The subsequent error handling paths\n   shouldn't go through ERR ZONE 1 again which leads to double free.\n\n   >>> Some initialization mainly on `gdev`.\n   >>> The rest of initialization.  Go to ERR ZONE 2 on errors.\n   >>> Chip registration success and exit.\n\n   >>> ERR ZONE 2.  gpio_device_put() and exit.\n   >>> ERR ZONE 1.",
