The nfsd debugfs files only\nreference module-global state and have no dependency on the slab\ncaches, so that reordering is a cleanup with no functional change.","state":0,"publishedAt":"2026-09-11T19:45:54.354+00:00","modifiedAt":"2026-10-19T08:50:41.624+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/nfsd/nfsctl.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"9fe5ea760e64f04412dbed51645a0dac7220d40a\",\n                            \"lessThan\": \"4ae5d7490ae6a7b83b3d607f88c499f4f85e753a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9fe5ea760e64f04412dbed51645a0dac7220d40a\",\n                            \"lessThan\": \"ab43ff94f5dfc2b6a080b167b69855eb7655c98b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9fe5ea760e64f04412dbed51645a0dac7220d40a\",\n                            \"lessThan\": \"2c390c8a1764d67095fe444401861fac4c049362\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/nfsd/nfsctl.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.50\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.4\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/4ae5d7490ae6a7b83b3d607f88c499f4f85e753a","https://git.kernel.org/stable/c/ab43ff94f5dfc2b6a080b167b69855eb7655c98b","https://git.kernel.org/stable/c/2c390c8a1764d67095fe444401861fac4c049362"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89668","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89668","identifiers":["CVE-2026-89668"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
