But the code assumes that at least\nETH_HLEN bytes are available and thus might read outside of the available\nbuffer.\n\nThe batadv_interface_tx() must therefore always check itself if enough data\nis available for the ethernet header and don't rely on min_header_len.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/38cd10b0aeec755d89f78722a2b83f4088ff0cb0","https://git.kernel.org/stable/c/49df66b7993c80b80c7eb9a84ba5b3410c8296a0","https://git.kernel.org/stable/c/58799078afebd5115e052bf69ad6697f9759dd6f","https://git.kernel.org/stable/c/6b4f521e01257387906f8b969ad3450d8208d4e2","https://git.kernel.org/stable/c/811fea37620f2097955d95ce81cfdba03fd30f1b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72232","score":0.00156,"percentile":0.04677,"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).
