The stid remains in the IDR and on the\nper-client list until the client is destroyed.\n\nRemove the layout stid from the per-client list and call\nnfs4_put_stid() to drop the creation reference.  When the\nrefcount reaches zero, nfsd4_free_layout_stateid() handles the\nremaining cleanup: cancelling the fence worker, removing from\nthe per-file list, and freeing the slab object.","state":0,"publishedAt":"2026-08-15T05:58:14.165+00:00","modifiedAt":"2026-10-16T18:55:32.624+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/nfs4state.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"1e33e1414bec54a4feafa9e67e2617031be0afe2\",\n                            \"lessThan\": \"7ed62f7040ee182cf7dea5798f9e114235b31dae\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1e33e1414bec54a4feafa9e67e2617031be0afe2\",\n                            \"lessThan\": \"da6f86ff4f2dd490bea52419a49e19680efd5847\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1e33e1414bec54a4feafa9e67e2617031be0afe2\",\n                            \"lessThan\": \"8024028ef91616cf91cc669f2446a0406bc0ba19\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1e33e1414bec54a4feafa9e67e2617031be0afe2\",\n                            \"lessThan\": \"86b9898920a6d02b4149f4fef9efd77b8aa3b9ca\",\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/nfs4state.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.9\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.9\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.97\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.40\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1.5\",\n                            \"lessThanOrEqual\": \"7.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/7ed62f7040ee182cf7dea5798f9e114235b31dae","https://git.kernel.org/stable/c/da6f86ff4f2dd490bea52419a49e19680efd5847","https://git.kernel.org/stable/c/8024028ef91616cf91cc669f2446a0406bc0ba19","https://git.kernel.org/stable/c/86b9898920a6d02b4149f4fef9efd77b8aa3b9ca"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-74316","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-74316","identifiers":["CVE-2026-74316"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
