This violates RFC 8881 section\n6.4.1.3: \"the ACL attribute is set as given\".\n\nThe issue occurs in nfsd_create_setattr(), which calls\nnfsd_attrs_valid() to determine whether to call nfsd_setattr().\nHowever, nfsd_attrs_valid() checks only for iattr changes and\nsecurity labels, but not POSIX ACLs. When only an ACL is present,\nthe function returns false, nfsd_setattr() is skipped, and the\nPOSIX ACL is never applied to the inode.\n\nSubsequently, when the client retrieves the ACL, the server finds\nno POSIX ACL on the inode and returns one generated from the file's\nmode bits rather than returning the originally-specified ACL.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":8.0},"cwes":["CWE-863"],"references":["https://git.kernel.org/stable/c/214b396480061cbc8b16f2c518b2add7fbfa5192","https://git.kernel.org/stable/c/381261f24f4e4b41521c0e5ef5cc0b9a786a9862","https://git.kernel.org/stable/c/60dbdef2ebc2317266a385e4debdb1bb0e57afe1","https://git.kernel.org/stable/c/75f91534f9acdfef77f8fa094313b7806f801725","https://git.kernel.org/stable/c/913f7cf77bf14c13cfea70e89bcb6d0b22239562"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-68803","score":0.00448,"percentile":0.38663,"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).
