A firmware response with\na length field larger than expected overruns the caller buffer and\nreads past the end of the reply allocation.\n\nReplace the dead -ENOMEM check with an active validation that\nreply->length fits within val_len before the memcpy.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/02886c18a340da59df57365f29009e1258bfe333","https://git.kernel.org/stable/c/71d140099165de03128c00dd129f1eab21c6a3c4","https://git.kernel.org/stable/c/7acb36fd60a3e7b858f12e69a919c3609b281408","https://git.kernel.org/stable/c/819d4c1323e2a9b7329021d5367aa01add22b5dc","https://git.kernel.org/stable/c/ce67ebe9d8629776ce38e6995ae72fb903c828db"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98830","score":0.002,"percentile":0.09712,"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).
