It\nneeds to be freed when of_device_register() fails. Call put_device() to\ngive up the reference that's taken in device_initialize(), so that it\ncan be freed in kobject_cleanup() when the refcount hits 0.\n\nmacio device is freed in macio_release_dev(), so the kfree() can be\nremoved.","modified":"2026-04-02T08:28:32.501941Z","published":"2025-10-04T15:16:35.537Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50474.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/19ded60b40e86b0903c8d5bd0161437ed5107a8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ac0a7059b7bcbed35bfffa34a82c9a9e99638ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/35858b87a943917fa30172aa4bf01ce7adbcb42c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3a866ff6fc2232c8e393cdb55ffb8ce947349e03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ca86eae55a2f006e6c1edd2029b2cacb6979515"},{"type":"WEB","url":"https://git.kernel.org/stable/c/76837e7f6b30da72ad59f56291e22804a219e015"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa9054267366ff0a382d403d17728e21951ddbb9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b29a2f1dd33ae9b94821ab2f4d398b9081786748"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca765257feb89dacf604ced9cd233db5f865dee0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50474.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50474"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1fa5ae857bb14f6046205171d98506d8112dd74e"},{"fixed":"3a866ff6fc2232c8e393cdb55ffb8ce947349e03"},{"fixed":"aa9054267366ff0a382d403d17728e21951ddbb9"},{"fixed":"35858b87a943917fa30172aa4bf01ce7adbcb42c"},{"fixed":"b29a2f1dd33ae9b94821ab2f4d398b9081786748"},{"fixed":"2ac0a7059b7bcbed35bfffa34a82c9a9e99638ef"},{"fixed":"19ded60b40e86b0903c8d5bd0161437ed5107a8b"},{"fixed":"ca765257feb89dacf604ced9cd233db5f865dee0"},{"fixed":"76837e7f6b30da72ad59f56291e22804a219e015"},{"fixed":"5ca86eae55a2f006e6c1edd2029b2cacb6979515"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50474.json"}}],"schema_version":"1.7.5"}
