{"id":"CVE-2026-89531","summary":"svcrdma: Reject connection when transport allocation fails","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsvcrdma: Reject connection when transport allocation fails\n\nhandle_connect_req() returns without action when\nsvc_rdma_create_xprt() fails to allocate the new transport.\nThe CM core returns 0 for CONNECT_REQUEST events, so it does\nnot destroy the new rdma_cm_id. Each allocation failure under\nmemory pressure leaks one rdma_cm_id, and a remote peer driving\nconnection attempts can amplify this.\n\nReject the connection by returning a non-zero status from the\nCM event handler, which tells the CM core to destroy the\norphaned cm_id.","modified":"2026-09-13T03:47:19.213437428Z","published":"2026-09-11T19:44:10.769Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89531.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0944462247dcb7de7622cdaaadf5f05c52707dab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f6a14c142fee4778c32709d1d54595c2e2b7991"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3cf372cec7ab2cd8c6002bf775cc14d90ccb098b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e21754bbf75075f3fee1cebc79f3417364235ec"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89531.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89531"},{"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":"377f9b2f4529e0ac702fd7b91e216afd0adc959e"},{"fixed":"6e21754bbf75075f3fee1cebc79f3417364235ec"},{"fixed":"3cf372cec7ab2cd8c6002bf775cc14d90ccb098b"},{"fixed":"1f6a14c142fee4778c32709d1d54595c2e2b7991"},{"fixed":"0944462247dcb7de7622cdaaadf5f05c52707dab"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89531.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.25"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89531.json"}}],"schema_version":"1.9.0"}
