If parsing a child fails, the failed child is\nnot counted in nr_children and the parent may be left with a children array\nthat bl_free_device() will not release when nr_children is zero.\n\nRelease the failed child and the already parsed children before returning the\nerror.  Also make bl_free_device() release the child array whenever the\nchildren pointer is set, so that partially initialised concat or stripe\ndevices are cleaned up correctly.\n\nbl_parse_scsi() can also fail after assigning d->bdev_file and dropping the\nfile reference.  Clear the pointer after fput() so that an outer cleanup path\ndoes not put it again.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1e1c36b206c659cf94c6755a1d821ed1babd32bc","https://git.kernel.org/stable/c/23e4162405c456ce12c772d5882d306135e828ae","https://git.kernel.org/stable/c/51d162dfb618f6cf3aa5e331c0305e27771ad884","https://git.kernel.org/stable/c/8a2494964edac2a13e82441c2bf887548dc3be0b","https://git.kernel.org/stable/c/c056f817e4200fb18079d5052c273a22f191ff0a"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90150","score":0.00213,"percentile":0.11538,"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).
