This preserves\nthe frame number for PTR_TO_STACK registers and keeps parent identity\nfields consistent.","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/29c239f8dbec5ab33a61796724d189bddee6cd4b","https://git.kernel.org/stable/c/8109c25e0c41f5f19a1c2380bb49c991a877494e","https://git.kernel.org/stable/c/86b203aadc2930e0a4f9c6277b5b80ff3664c472","https://git.kernel.org/stable/c/8cb23101a3fcc7432b451ea3d0f14a90711f4acf","https://git.kernel.org/stable/c/a4c6f804b44c5c790269b25e0e61cf4e9f117c86"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-74720","score":0.00129,"percentile":0.02545,"date":"2026-10-26"},"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).
