Other topology parser paths validate these fields with bounded\nstrnlen() checks before using them as C strings, but the PCM and DAI\npaths still pass some fixed-size arrays directly to strlen(),\ndevm_kstrdup(), DAI lookup, and diagnostic prints.\n\nA malformed topology blob with a non-NUL-terminated PCM, DAI, or stream\ncapability name can therefore make the parser read past the end of the\nfixed-size field.\n\nReject unterminated PCM and DAI name fields before consuming them as C\nstrings.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/473f7d25d93e80db526a9d05887f0071abdc6d9b","https://git.kernel.org/stable/c/5c2537cf24d673956b4e58029001667f89586fa2","https://git.kernel.org/stable/c/b7e44d1986d6671342c19b82192189ca5db5dab7","https://git.kernel.org/stable/c/ba37b62ed0a443b8e23f53a7477e7f2537fd34c7","https://git.kernel.org/stable/c/c405b07246bf179e9457de57501c3470175b165e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74291","score":0.00168,"percentile":0.06052,"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).
