If the driver is unloaded in\nthis scenario, it calls ndo_stop again, attempting to free\nresources that have already been freed, leading to a host\nhang issue. To resolve this, dev_close should be called\ninstead of the device-specific stop function.dev_close\ninternally calls ndo_stop to stop the network interface\nand performs additional cleanup tasks. During the driver\nunload process, if the device is already down, ndo_stop\nis not called.","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-415"],"references":["https://git.kernel.org/stable/c/34f42736b325287a7b2ce37e415838f539767bda","https://git.kernel.org/stable/c/6d1052423518e7d0aece9af5e77bbc324face8f1","https://git.kernel.org/stable/c/7e1ca1bed3f66e00377f7d2147be390144924276","https://git.kernel.org/stable/c/c8d788f800f83b94d9db8b3dacc1d26be38a6ef4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-37933","score":0.00207,"percentile":0.10844,"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).
