"value": "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."
