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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpio/gpiolib.c"],"versions":[{"version":"aab5c6f200238ac45001bec3d5494fff8438a8dc","lessThan":"f0cf9c7b7c281956cc0dec163132cd96f76e1d60","status":"affected","versionType":"git"},{"version":"aab5c6f200238ac45001bec3d5494fff8438a8dc","lessThan":"fb4584d2b324c522404c733c65840a1a6519ada8","status":"affected","versionType":"git"},{"version":"aab5c6f200238ac45001bec3d5494fff8438a8dc","lessThan":"16fdabe143fce2cbf89139677728e17e21b46c28","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpio/gpiolib.c"],"versions":[{"version":"6.9","status":"affected"},{"version":"0","lessThan":"6.9","status":"unaffected","versionType":"semver"},{"version":"6.18.22","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.12","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.18.22"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.19.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f0cf9c7b7c281956cc0dec163132cd96f76e1d60"},{"url":"https://git.kernel.org/stable/c/fb4584d2b324c522404c733c65840a1a6519ada8"},{"url":"https://git.kernel.org/stable/c/16fdabe143fce2cbf89139677728e17e21b46c28"}],"title":"gpio: Fix resource leaks on errors in gpiochip_add_data_with_key()","x_generator":{"engine":"bippy-1.2.0"}}}}
