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": "a500e1837c4266ddb05b39b3e1cc71f49a43ffa5", "status": "affected", "versionType": "git" }, { "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": "6.12.95", "lessThanOrEqual": "6.12.*", "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": "6.12.95" }, { "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/a500e1837c4266ddb05b39b3e1cc71f49a43ffa5" }, { "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" } } } }
