On the path\nwhere the host queue backlog is exceeded and the function returns\nNVME_SC_CONNECT_CTRL_BUSY, reference of ndev is not released, leaking\nthe kref.\n\nFix this by adding a goto to the existing put_device label before the\nearly return.","modified":"2026-09-06T03:30:26.531587863Z","published":"2026-07-25T08:49:49.541Z","related":["openSUSE-SU-2026:11476-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64321.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5828517d17eda27f21d29ea14800c9e0a57bad11"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8803c4f0ac3fa7df5551bbb5a8800c434a94357"},{"type":"WEB","url":"https://git.kernel.org/stable/c/badc53620fe813b3a9f727ef9526f98567c2c898"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d65fe42820b890a6a4644de0a95a812471f79ad3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64321.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64321"},{"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":"31deaeb11ba7a885116c9c30892b9f763c04d59c"},{"fixed":"d65fe42820b890a6a4644de0a95a812471f79ad3"},{"fixed":"a8803c4f0ac3fa7df5551bbb5a8800c434a94357"},{"fixed":"5828517d17eda27f21d29ea14800c9e0a57bad11"},{"fixed":"badc53620fe813b3a9f727ef9526f98567c2c898"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64321.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64321.json"}}],"schema_version":"1.9.0"}
