CVE-2026-72186

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

Description An issue exists in the NTFS driver where system files, such as $Bitmap, can be exposed via show sys files and written to from userspace. This action leads to volume corruption. Additionally, because the cluster allocator scans $Bitmap through the same inode's page cache, writing to $Bitmap can cause a deadlock during writeback against the folio it already holds locked. These base metadata files are intended to be maintained solely by the driver and should not be modified through the file interface.

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