That assumes\nthe parameter index matches the UBI device number.\n\nThat assumption is not true when mtd= specifies an explicit ubi_num. A\nsuccessfully attached device can be stored at a higher ubi_devices[]\nslot, and a later failure can miss it during rollback.\n\nScan the full ubi_devices[] array and detach by the actual array index,\nmatching the way UBI devices are stored.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4417ab6ecad01cf2d01045ef8104c95a66b0e893","https://git.kernel.org/stable/c/552e565ed8846e7db143e4a6bdf3f5677453c686","https://git.kernel.org/stable/c/5b0a6b554e12a97f9771a9a9f4ea1f5457373c73","https://git.kernel.org/stable/c/6b92e66ec6dd8019e8efb2a568ef7c967c5a18c5","https://git.kernel.org/stable/c/83c978921688af40dcab6db74882d1ff9b0b765c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90216","score":0.00177,"percentile":0.07165,"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).
