However, when -ENOMEM hits at the middle of the\nsync EP URB allocation loop, the partially allocated URBs might be\nleft without released, because ep->nurbs is still zero at that point.\n\nFix it by setting ep->nurbs at first, so that the error handler loops\nover the full URB list.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/0604e5e5537af099ea2f6dfd892afe5c92db8a80","https://git.kernel.org/stable/c/0672215994e2347a9b4f145e2bc1709b1e01cee3","https://git.kernel.org/stable/c/28d8d267af5d73f91d7640cbdb4024703256e36c","https://git.kernel.org/stable/c/46f0aed47673e275d682af60ed26dcc28add8eae","https://git.kernel.org/stable/c/6382da0828995af87aa8b8bef28cc61aceb4aff3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2022-50484","score":0.00163,"percentile":0.0552,"date":"2026-11-01"},"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).
