This would allow the\ncdata->rhdr.hdr.size comparison to pass with mismatched sizes,\npotentially leading to out-of-bounds access in snd_sof_update_control.\n\nUse check_mul_overflow() and check_add_overflow() to detect and reject\noverflowed size calculations.","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/312c7d2ebe696da3f885eee77d52297664e57c53","https://git.kernel.org/stable/c/6856b3c23b0995eefad5a6142b4365ef70e1fe4a","https://git.kernel.org/stable/c/711d912b18763af62a63aa8f2419a774eb63bba4","https://git.kernel.org/stable/c/8791977d7289f6e9d2b014f60a5455f053a7bc04","https://git.kernel.org/stable/c/89a2309a9eec80d4c19e3aed62c4f923594d1911"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72302","score":0.00177,"percentile":0.07255,"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).
