A truncated frame can\ntherefore cause out-of-bounds reads or leave insufficient data for the\nEthernet address writes.\n\nReject frames that do not contain the base 802.11 header and data\nframes that do not contain their complete calculated header span.","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/6829665d050983907b560173e49dcc6c11cb2730","https://git.kernel.org/stable/c/7b0f62d2986a28e5e4188366bc2f4e2868b14790","https://git.kernel.org/stable/c/7edd3adb0c80d70b4237640275c559610f438476","https://git.kernel.org/stable/c/8b3e4ed9c35d3d3b64fcc23f4a1f22b37c1865b1","https://git.kernel.org/stable/c/a3ac6d849de5f7abe14761d741bbb843ac793454"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-74648","score":0.00129,"percentile":0.02532,"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).
