However, mport->net is left pointing at the freed object.\n\nA later mport unregister path can then dereference the dangling mport->net\npointer and may try to free the same rio_net again.\n\nClear mport->net in the rio_add_net() failure path, matching the cleanup\ndone for the destID table allocation failure path.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/24f60ebabeb8757cec8ec2f97660d521bc9147ec","https://git.kernel.org/stable/c/332591a245de978349a7558f8b20469951bb77cc","https://git.kernel.org/stable/c/3f00999e44d9984036a029dbad9d2afe94a674d0","https://git.kernel.org/stable/c/44a37264b26911e13d0a4f5630751c4157ed0354","https://git.kernel.org/stable/c/530a9d5ef831a0049dad9a6b2b92d02301352c38"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90319","score":0.0021,"percentile":0.11158,"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).
