This reduces the\nnumber of available URBs per error by 1. This leads to reduced performance\nand ultimately to a complete stop of the transmission.\n\nIf the sending of a bulk URB fails do proper cleanup:\n- increase netdev stats\n- mark the echo_sbk as free\n- free the driver's context and do accounting\n- wake the send queue","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1a588c40a422a3663a52f1c5535e8fb6b044167d","https://git.kernel.org/stable/c/4a82072e451eacf24fc66a445e906f5095d215db","https://git.kernel.org/stable/c/516a0cd1c03fa266bb67dd87940a209fd4e53ce7","https://git.kernel.org/stable/c/87974ebd6552817492daec7866ebfa2c484fa2ac","https://git.kernel.org/stable/c/9c8eb33b7008178b6ce88aa7593d12063ce60ca3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68307","score":0.00193,"percentile":0.0883,"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).
