Although the\ninitial reply-size check includes a vendor count byte in the fixed layout,\nit does not guarantee that the byte remains after the standard codec array.\n\nIf a controller reply ends immediately after that array, calculating the\nvendor codec array size reads vnd_codecs->num beyond the skb data.  Use\nskb_pull_data() to validate and consume each codec header before using its\ncount in both command variants.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/12a82819b0cada6e304790b1097f8f9006eb6123","https://git.kernel.org/stable/c/9c04b9a4d08b95dee901d24b7607c4cbd65fa0a8","https://git.kernel.org/stable/c/a6da782fefae611e68a1aa79644065fc8ca5abcd","https://git.kernel.org/stable/c/d0795cfd6f655f4de84868a4f4bb41a03f037b3d","https://git.kernel.org/stable/c/e4cfd3c4299105237458b27958bd7b0aa4c60795"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98247","score":0.00211,"percentile":0.11293,"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).
