Take a compensating\n__module_get() before the svc_xprt_put() to keep the count\nbalanced, matching the convention in svc_rdma_accept()'s error\npath.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2e35ec558b8cece9399a50141ecaeadbdb8768dc","https://git.kernel.org/stable/c/ac1dd6002f758ab7dd3e737757e5a1bb1c0b38d6","https://git.kernel.org/stable/c/e346ef7bcb137f50c49f969330ab7dcf64ea1654","https://git.kernel.org/stable/c/e68380710fc970e07610b2f42594575ad35fdb1c","https://git.kernel.org/stable/c/ee70d690b5544b736706a9a5796aafb634013f54"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-89527","score":0.00217,"percentile":0.12002,"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).
