The legacy nfsd4_decode_nfstime4 has this\ncheck but the TIME_DELEG paths do not. A malformed timespec can\npropagate through notify_change() to disk.\n\nAdd range checks in both nfs4xdr.c (SETATTR path) and\nnfs4callback.c (CB_GETATTR path).","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0f4a767340fad392bd656115b8752005518c9065","https://git.kernel.org/stable/c/5eb489831a9fd4754f4baf26e6989efb66ce104c","https://git.kernel.org/stable/c/7e7b93da7fa2e77f977096251899d1410986adf6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89701","score":0.00206,"percentile":0.10606,"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).
