If the firmware returns a response\nshorter than 520 bytes (8 + 512), this reads beyond the skb data\nbuffer. The over-read data is then returned to userspace via nla_put()\nin mt7925_testmode_dump().\n\nAdd a length check before the memcpy to ensure the skb contains\nsufficient data.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/c386e90a7ce8ddec9f038e9437661a2821b0ce89","https://git.kernel.org/stable/c/c7369a00860a0704461d440e7c3bf9b49bfdbaee","https://git.kernel.org/stable/c/e8b214b6d6e1902025452db0a0af73dc9693e4ba"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74324","score":0.00206,"percentile":0.1072,"date":"2026-11-01"},"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).
