CVE-2025-71311

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ntfs3 file system where new folios are not properly initialized before use. This occurs when new folios are allocated without being marked as uptodate and the ni read frame() function is skipped because the caller expects the frame to be completely overwritten. Consequently, some reserved folios may remain only partially filled, leaving the remaining memory uninitialized. This was identified via KMSAN in the longest match std() function, which is invoked from ntfs compress write().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
