If\nthe CREATE succeeds but a later command returns an error, the function\nmust retain the CREATE FID so common cleanup can issue SMB2_close(). It\nalso must not treat a response error as a valid CREATE.\n\nValidate the CREATE response before using its fields, record the FIDs, and\nmark the handle open before handling errors from later compound commands.\nMove the -EREMCHG reconnect handling before response validation so a\nmissing response does not hide the reconnect request. Count the handle\nwhen it is marked open; confirmed close responses decrement the counter,\nwhile existing close retry behavior remains best effort on transport\nfailures.","state":0,"publishedAt":"2026-10-18T15:15:02.436+00:00","modifiedAt":"2026-10-19T09:19:47.547+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/smb/client/cached_dir.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"b0f6df737a1c5d9d5ff90cc946205d8af46cc067\",\n                            \"lessThan\": \"48958ddda3d7eee3600261e2d90671f63e055dc4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"b0f6df737a1c5d9d5ff90cc946205d8af46cc067\",\n                            \"lessThan\": \"abab661eed00fa102d3c35ddf1cce4f687e718c1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"b0f6df737a1c5d9d5ff90cc946205d8af46cc067\",\n                            \"lessThan\": \"7c1509598a4fdfb54cb09ce33e4405bd6dbd8295\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"b0f6df737a1c5d9d5ff90cc946205d8af46cc067\",\n                            \"lessThan\": \"d2ff5fb93ea83034025850266b5eed391f96b825\",\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/smb/client/cached_dir.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"5.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.112\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.55\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.9\",\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":[],"references":["https://git.kernel.org/stable/c/48958ddda3d7eee3600261e2d90671f63e055dc4","https://git.kernel.org/stable/c/abab661eed00fa102d3c35ddf1cce4f687e718c1","https://git.kernel.org/stable/c/7c1509598a4fdfb54cb09ce33e4405bd6dbd8295","https://git.kernel.org/stable/c/d2ff5fb93ea83034025850266b5eed391f96b825"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98452","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98452","identifiers":["CVE-2026-98452"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
