All other error paths in the\nfunction jump to the cleanup label that ends with\nmlxsw_sp_lag_put(), so this is a single missed release.\n\nFix the leak by replacing the bare 'return err' with a goto to the\nexisting error cleanup label, which will drop the reference safely.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1cf8a1af42b1f12a30b7abd34fe4fc23b3170e7e","https://git.kernel.org/stable/c/2d8b3c3e129973a51ae924bdcf6993a76b828814","https://git.kernel.org/stable/c/3fbeaa8ecd144ad593f9fa1ab4b40a780ad3700b","https://git.kernel.org/stable/c/41c8c1d65b32beacd8d916a22457b4f6e47f45af","https://git.kernel.org/stable/c/8b3350eacd9df0597bfe36a594df7b9def0b3edf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72308","score":0.0022,"percentile":0.12574,"date":"2026-10-31"},"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).
