However, scmi_device_destroy() uses the same protocol/name\nlookup to find devices that must be unregistered during channel teardown.\n\nSplit the match helper so driver matching still skips transport devices,\nwhile explicit child lookup can find them for teardown. Use a shared\ntransport-device name prefix macro for both matching and name generation.\n\nSince transport-device names are derived from direction and protocol ID,\nreject duplicate protocol channel setup before creating or finding a\ntransport device. This prevents malformed firmware with duplicate\nprotocol child nodes from reusing an existing transport device and then\ndestroying it when the duplicate IDR insertion fails.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4635953b4c1af477e166073521a77de6279f6929","https://git.kernel.org/stable/c/a14dd8fe0a95db638c550ed984cfe2a7428c783d","https://git.kernel.org/stable/c/c656427440ea627166394d00c4b72147d5d79c60"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93080","score":0.00206,"percentile":0.10606,"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).
