一、漏洞信息
漏洞编号：CVE-2025-40067
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.12.33,6.18.18,6.4.0,6.6.0
CVSS评分：
BaseScore：7.8 High
Vector：CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:fs/ntfs3: reject index allocation if $BITMAP is empty but blocks existIndex allocation requires at least one bit in the $BITMAP attribute totrack usage of index entries. If the bitmap is empty while index blocksare already present, this reflects on-disk corruption.syzbot triggered this condition using a malformed NTFS image. During arename() operation involving a long filename (which spans multipleindex entries), the empty bitmap allowed the name to be added withoutvalid tracking. Subsequent deletion of the original entry failed with-ENOENT, due to unexpected index state.Reject such cases by verifying that the bitmap is not empty when indexblocks exist.
