Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
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，以下漏洞已得到修复： ntfs：在 ntfs_setattr_size() 中获取 invalidate_lock 函数在更新 并调整磁盘属性大小时，并未持有 。由于缺页异常（page fault）会以共享模式获取该锁，因此当缺页异常与调整大小操作发生竞争时，可能会针对 的临时运行列表（runlist）状态解析虚拟簇号（VCN），从而引发虚假的 信号；此外，该异常还可能与调整大小的收尾操作（包括 、 和 ）发生交错，导致状态不一致。 修复方案是：在调用 之后，在整个调整大小操作期间独占地获取

Vulnerability Title
ntfs: take invalidate_lock in ntfs_setattr_size()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: take invalidate_lock in ntfs_setattr_size() ntfs_setattr_size() updates i_size and resizes the on-disk attribute without holding mapping->invalidate_lock. Page faults take the lock shared, so a fault racing the resize can resolve a VCN against the transient runlist state of ntfs_non_resident_attr_expand() and fail with a spurious SIGBUS, and can interleave with the size-change epilogue (truncate_pagecache(), i_size_write(), pagecache_isize_extended()). Take invalidate_lock exclusively around the whole resize after inode_dio_wait(), matching the fallocate path and other filesystems such as xfs, which wraps truncate in its mmaplock (= invalidate_lock).
