If kvm_init() fails its\nresult is returned directly, but since module_init() does not run the\nmodule_exit() stuff on failure, so kvm_loongarch_env_exit() is never\ncalled and those resources are leaked.\n\nSo call kvm_loongarch_env_exit() when kvm_init() fails, matching the\nteardown-on-failure pattern used by riscv_kvm_init().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3bf6f5e2e1007d38a5f35bd37e94ab645a0c40bc","https://git.kernel.org/stable/c/6b78786ee7260d9818cf1d7a245b7a655ef83076","https://git.kernel.org/stable/c/6bbbd7b719233645a5c120557a9ca1422e6b7a48","https://git.kernel.org/stable/c/f7a1064cce3b100b54780c68529176232d8eb01e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89909","score":0.00209,"percentile":0.10935,"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).
