Therefore, partial\nallocation should not be treated as a fatal error.\n\nModify es58x_alloc_rx_urbs() to return 0 if at least one URB has been\nallocated, restoring the intended behavior and preventing the leak\nin es58x_open().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/611e839d2d552416b498ed5593e10670f61fcd4d","https://git.kernel.org/stable/c/6c5124a60989051799037834f0a1a4b428718157","https://git.kernel.org/stable/c/97250eb05e4b6afe787290e8fd97d0675116c61b","https://git.kernel.org/stable/c/aec888f44853584b5a7cd01249806030cf94a73d","https://git.kernel.org/stable/c/b1979778e98569c1e78c2c7f16bb24d76541ab00"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-23037","score":0.00243,"percentile":0.15515,"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).
