If the new data has a different size, the copy\nuses the wrong length: it may truncate valid data or copy stale bytes.\n\nFix by validating and using the incoming data's sof_abi_hdr.size from\nucontrol before copying.","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/038406abde0d0883419ec89425ea941ec8bbef95","https://git.kernel.org/stable/c/266f936db83aee6ca6473bbb06259bda52bf4fc3","https://git.kernel.org/stable/c/3ad673e7139cf214afd24321a829aad6575f4163","https://git.kernel.org/stable/c/4cf6a7ebbf8787393b158b2cc341723e5bebc4a8","https://git.kernel.org/stable/c/fb4293173db2d474d8fbc0e5ecf4943e6df2b40e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72304","score":0.00163,"percentile":0.05497,"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).
