All callers pass an uninitialized\nstack variable and afterwards feed it to avc_audit(), and the inode hook\neven stores it in the per-task decision cache.\n\nFill in a deny-all, audit-all decision, similar to avd_init(), so every\ncaller receives a defined value at no cost on the hot path.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/24e00850bcff46b984f4c44b92e5499450fcfb5a","https://git.kernel.org/stable/c/5a6f9a872b4ff68877caf998bee352153b7154bc","https://git.kernel.org/stable/c/835133337c2ce200db56f62d018c79087dee2603","https://git.kernel.org/stable/c/8861db305103107199b1426f25fde1fb6d465583","https://git.kernel.org/stable/c/c781e737aa0de95289b1774d5fd29388895737a9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-98413","score":0.0022,"percentile":0.12409,"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).
