A sparse class value is absorbed by\npolicydb_class_isvalid() and its siblings; booleans have no such\npredicate, and no consumer that could use one.\n\nReject a boolean value that no boolean defines, once, where the array is\nbuilt. Conforming policies define every boolean they declare and are\nunaffected.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3161daa3f1e3ca68f8b2b8fa01720b5a8dcc6b40","https://git.kernel.org/stable/c/3938c8494d3c5d84a53fd7d1966ae9dde46cb5f8","https://git.kernel.org/stable/c/42a7107f99d86a7524c37f108047dfa3db096ab5","https://git.kernel.org/stable/c/4d0ece18e648bd4362704fd087249ac697f2b7fb","https://git.kernel.org/stable/c/4dfb997c60f7951011d3dcbee926e3a7f80d8a76"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80913","score":0.00165,"percentile":0.05662,"date":"2026-10-31"},"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).
