{"id":"CVE-2022-50234","summary":"io_uring/af_unix: defer registered files gc to io_uring release","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/af_unix: defer registered files gc to io_uring release\n\nInstead of putting io_uring's registered files in unix_gc() we want it\nto be done by io_uring itself. The trick here is to consider io_uring\nregistered files for cycle detection but not actually putting them down.\nBecause io_uring can't register other ring instances, this will remove\nall refs to the ring file triggering the -\u003erelease path and clean up\nwith io_ring_ctx_free().\n\n[axboe: add kerneldoc comment to skb, fold in skb leak fix]","modified":"2026-04-02T08:28:21.052963Z","published":"2025-09-15T14:01:38.199Z","related":["SUSE-SU-2025:03613-1","SUSE-SU-2025:03615-1","SUSE-SU-2025:03626-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3761-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50234.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0091bfc81741b8d3aeb3b7ab8636f911b2de6e80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/04df9719df1865f6770af9bc7880874af0e594b2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75e94c7e8859e58aadc15a98cc9704edff47d4f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/813d8fe5d30388f73a21d3a2bf46b0a1fd72498c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4293c01ee0d0ecdd3cb5801e13f62271144667a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c378c479c5175833bb22ff71974cda47d7b05401"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50234.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50234"},{"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":"6b06314c47e141031be043539900d80d2c7ba10f"},{"fixed":"04df9719df1865f6770af9bc7880874af0e594b2"},{"fixed":"c378c479c5175833bb22ff71974cda47d7b05401"},{"fixed":"813d8fe5d30388f73a21d3a2bf46b0a1fd72498c"},{"fixed":"b4293c01ee0d0ecdd3cb5801e13f62271144667a"},{"fixed":"75e94c7e8859e58aadc15a98cc9704edff47d4f2"},{"fixed":"0091bfc81741b8d3aeb3b7ab8636f911b2de6e80"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50234.json"}}],"schema_version":"1.7.5"}
