Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： ntfs：将任何非零的 dio zero-range 返回值视为错误 ntfs_dio_zero_range() 函数要么返回 0，要么返回来自 blkdev_issue_zeroout() 的负 errno 错误码；它绝不会返回正值。因此，ntfs_attr_fallocate() 中的零填充失败检查从未被触发，导致零填充操作失败时被静默忽略：循环继续执行，新分配的簇被合并到 initialized_size 中，写入操作可能成功，但磁盘上残留了陈旧数据。 现在，将任何非

Vulnerability Title
ntfs: treat any nonzero dio zero-range return as an error
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: treat any nonzero dio zero-range return as an error ntfs_dio_zero_range() returns either 0 or a negative errno from blkdev_issue_zeroout(); it never returns a positive value. The zeroing failure check in ntfs_attr_fallocate() therefore never fired, so a failed zeroing operation was silently ignored: the loop kept going, the newly allocated clusters were folded into initialized_size and the write could succeed leaving stale on-disk data. Treat any nonzero return as an error and abort the allocation.
