However the\ncorrect handling of EBUSY was missing and has been added as a return\ncode indicating a successful transfer to the crypto engine.","modified":"2026-09-27T03:47:38.374334948Z","published":"2026-09-25T10:22:08.694Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97591.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/203702f0013f9b7324e8c5facb6cd6e9c0942b13"},{"type":"WEB","url":"https://git.kernel.org/stable/c/330148371401de474b656eaf521861f12ec1a1ce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bcd7f1f1e2f2882ad206f72425255be105178151"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97591.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97591"},{"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":"cbbc675506cc4cd93e6f895e7c1f693156f9a95c"},{"fixed":"203702f0013f9b7324e8c5facb6cd6e9c0942b13"},{"fixed":"bcd7f1f1e2f2882ad206f72425255be105178151"},{"fixed":"330148371401de474b656eaf521861f12ec1a1ce"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97591.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97591.json"}}],"schema_version":"1.9.0"}
