However, it's simpler to store the return in\nan int ret variable.\n\nThis bug would eventually result in a crash when dereference the invalid\nerror pointer.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-190"],"references":["https://git.kernel.org/stable/c/61f28012e5650c619223decdb7970e0d3162e949","https://git.kernel.org/stable/c/a187883cc1dc784a4d32537f5d316f1b7b9ad76f","https://git.kernel.org/stable/c/a1cc432cb0b0a1f74f98a0db3b94ca880c7947ac","https://git.kernel.org/stable/c/aa37f5fef78dd11cbf983269da2031e12625c56d","https://git.kernel.org/stable/c/cad756733dc3985188983f3e2eb77e2927209099"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-64598","score":0.00278,"percentile":0.20023,"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).
