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：修复传递给 ntfs_attr_record_resize 的错误 MFT 记录指针 ntfs_new_attr_flags() 函数将错误的 MFT 记录传递给了 ntfs_attr_record_resize()。当属性位于扩展记录（extent record）中时，ctx->mrec 指向该扩展记录，但函数接收到的却是基础记录指针 m，导致 memmove 中的大小计算出现错误。 修复方法：将 ctx->mrec（即包含该属性的实际 MFT 记录）而非

Vulnerability Title
ntfs: fix incorrect MFT record pointer passed to ntfs_attr_record_resize
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: fix incorrect MFT record pointer passed to ntfs_attr_record_resize ntfs_new_attr_flags() passes the wrong MFT record to ntfs_attr_record_resize(). When the attribute is in an extent record, ctx->mrec points to the extent but the function receives the base record pointer m, causing incorrect size calculations in memmove. Fix by passing ctx->mrec (the actual MFT record containing the attribute) instead of m (the base MFT record) to ntfs_attr_record_resize().
