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().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/18c5781ed8bc2f423c26ec93e47e2057cd76a783","https://git.kernel.org/stable/c/5e820d04c241c81a47e1940349018690e93d8167","https://git.kernel.org/stable/c/acc173608ca7abe5dee8983086b44efd8b0dbc84","https://git.kernel.org/stable/c/bb0251991420c25e3ceeac40ea09250d79ed7ef0","https://git.kernel.org/stable/c/bd764baf82bb46e958a0bd0b481630dd71313055"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90411","score":0.00216,"percentile":0.11955,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
