{"id":"CVE-2026-90411","summary":"nvme-fc: unmap cmd_iu DMA on rsp_iu mapping failure in init_request","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-fc: unmap cmd_iu DMA on rsp_iu mapping failure in init_request\n\n__nvme_fc_init_request() maps cmd_iu and then rsp_iu for DMA. If the\nrsp_iu mapping fails, the original code only recorded the error and fell\nthrough: it left the already-mapped cmd_iu unmapped and still marked the\nop as FCPOP_STATE_IDLE before returning. Since blk-mq does not call\n.exit_request() when .init_request() fails, the cmd_iu mapping is leaked\nfor every op whose rsp_iu mapping fails.\n\nJump to an error path on rsp_iu mapping failure that unmaps cmd_iu and\nreturns the error without marking the op idle, so it stays in the\nFCPOP_STATE_UNINIT state set by the initial memset().","modified":"2026-09-18T03:48:38.369082019Z","published":"2026-09-17T16:09:38.077Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90411.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/18c5781ed8bc2f423c26ec93e47e2057cd76a783"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e820d04c241c81a47e1940349018690e93d8167"},{"type":"WEB","url":"https://git.kernel.org/stable/c/acc173608ca7abe5dee8983086b44efd8b0dbc84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb0251991420c25e3ceeac40ea09250d79ed7ef0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd764baf82bb46e958a0bd0b481630dd71313055"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be5eb47ee3fea338efae1a5b678d6bb5f0fcc931"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0892cfb60a75e2c86ba8e2127b133f6549c12b3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f49d0c3a8d56a7cda1628ae17341a4a42063563c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90411.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90411"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e399441de9115cd472b8ace6c517708273ca7997"},{"fixed":"c0892cfb60a75e2c86ba8e2127b133f6549c12b3"},{"fixed":"5e820d04c241c81a47e1940349018690e93d8167"},{"fixed":"bb0251991420c25e3ceeac40ea09250d79ed7ef0"},{"fixed":"acc173608ca7abe5dee8983086b44efd8b0dbc84"},{"fixed":"18c5781ed8bc2f423c26ec93e47e2057cd76a783"},{"fixed":"bd764baf82bb46e958a0bd0b481630dd71313055"},{"fixed":"be5eb47ee3fea338efae1a5b678d6bb5f0fcc931"},{"fixed":"f49d0c3a8d56a7cda1628ae17341a4a42063563c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90411.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90411.json"}}],"schema_version":"1.9.0"}
