This hides the error condition from the caller of\nregcache_init(), and can cause NULL pointer dereferences when the regcache\nis later accessed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/9108f7fa493b4c88cbc09503e0c164244456bad5","https://git.kernel.org/stable/c/9f171aa115ec76be02c76c5765cd2c865279e34a","https://git.kernel.org/stable/c/bae057687f61580dd897411cd749da22a7740647"],"products":[],"source":"nvd","synced_at":"2026-10-26T16:34:44.474829350+00:00"},"epss":{"cve":"CVE-2026-72453","score":0.00198,"percentile":0.09435,"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).
