This\nleaves a dangling pointer in the array. Then cdx_destroy_res_attr()\nfrees the already-freed memory. Fix the double free by initializing\ncdx_dev->res_attr[num] after sysfs_create_bin_file() completes.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4cd24873ab9fdbd730604881a6e8087bc7b99336","https://git.kernel.org/stable/c/6f4acc3a3c300e174e3f586b97b04ed8f5948c36","https://git.kernel.org/stable/c/7e9451bf0bdba6daee1eaf4e7566612af6ca1c32","https://git.kernel.org/stable/c/88f4cd42a04bdadd189d7f667a4c279f4e962ca6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93215","score":0.00168,"percentile":0.06012,"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).
