Page faults take the lock\nshared, so a fault racing the resize can resolve a VCN against the\ntransient runlist state of ntfs_non_resident_attr_expand() and fail\nwith a spurious SIGBUS, and can interleave with the size-change\nepilogue (truncate_pagecache(), i_size_write(),\npagecache_isize_extended()).\n\nTake invalidate_lock exclusively around the whole resize after\ninode_dio_wait(), matching the fallocate path and other filesystems\nsuch as xfs, which wraps truncate in its mmaplock (= invalidate_lock).","state":0,"publishedAt":"2026-10-28T10:34:17.224+00:00","modifiedAt":"2026-10-28T10:34:17.224+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/ntfs/file.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"9c87959601e80b39a45250e362e6ddfec17cb0fa\",\n                            \"lessThan\": \"f0b0738ba95731eeafd11352c74f8b48951f67dc\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9c87959601e80b39a45250e362e6ddfec17cb0fa\",\n                            \"lessThan\": \"9cc5761b8f28f9cef72061094eb5e37e2cd44d97\",\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/ntfs/file.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.13\",\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/f0b0738ba95731eeafd11352c74f8b48951f67dc","https://git.kernel.org/stable/c/9cc5761b8f28f9cef72061094eb5e37e2cd44d97"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-99102","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-99102","identifiers":["CVE-2026-99102"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
