Quick assessment

Affected
Linux Linux
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.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 7.1.5之前版本存在安全漏洞，该漏洞源于在调整NTFS常驻属性大小时，可能将0字节$DATA属性转换为非常驻属性，导致fsck检查时将其视为损坏。

Vulnerability Title
ntfs: not change 0-byte $DATA attribute to non-resident
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: not change 0-byte $DATA attribute to non-resident When ntfs_resident_attr_resize() cannot grow a resident attribute in place, it retries after converting other resident attributes to non-resident to free space in the MFT recrord. Do not select zero-length resident $DATA attributes for this conversion. fsck treats 0-byte non-resident $DATA attribute as corruptions.
