This avoids issues like memory leaks when drivers are unbound\nwithout their devices being physically disconnected (e.g. on probe\ndeferral or configuration changes).\n\nFix the controller and driver data lifetime so that they are released\non driver unbind.\n\nNote that this also makes sure that the SPI controller is placed\ncorrectly under the USB interface in the device tree.","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/108a64b27a52f781c4f3751641e3dd65c7dd2fb5","https://git.kernel.org/stable/c/42dfcd2ced905ea3993d88a051c13e04ab1029f7","https://git.kernel.org/stable/c/4422fc2411cbbdf5104a914e0596bb483faea254","https://git.kernel.org/stable/c/abe572f630bc1f0e77041012ab075869036ede4f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-46228","score":0.00119,"percentile":0.01759,"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).
