A short response or oversized BSS length can\ntherefore underflow tlv_buf_size and make the TLV parser walk beyond the\ncommand response.\n\nCompute the fixed extent from the selected normal or background scan\nresponse. Validate that the fixed fields and BSS data fit before deriving\nthe TLV extent and entering the parser.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/25217c5f6ce0bf3004f80c129464cd35fe9a420f","https://git.kernel.org/stable/c/3687d7d48070838cc2953431b3a27717cab0aaf6","https://git.kernel.org/stable/c/48312f0085aa1577d6d41af2a079b34de17c1a57","https://git.kernel.org/stable/c/7106ad8b74f50cca1ef36131f327d2c78f556daa","https://git.kernel.org/stable/c/9cff2f39ed38a32070b08364c4c9346e85b8f9ec"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98185","score":0.00177,"percentile":0.07174,"date":"2026-10-26"},"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).
