CVE-2025-71289 is a flaw in the Linux kernel's ntfs3 filesystem code. During file truncation, if attr_set_size() fails while shrinking a file, the error is silently ignored instead of being propagated and handled correctly. As a result, the inode can be left in an inconsistent state after the truncate operation. The issue is specifically described as affecting the ntfs3 path handling file size reduction, where failure handling in the truncation logic was incomplete.
