Description
A flaw was found in the Linux kernel's NTFS filesystem driver. When an attempt to mount an NTFS volume fails, the ntfs_fill_super() function's error handling path does not properly free all volume-wide resources. This oversight leads to a silent resource leak, where memory and other resources accumulate with each failed mount attempt. A local attacker could exploit this by repeatedly attempting to mount an NTFS filesystem, potentially leading to a Denial of Service (DoS) due to resource exhaustion.
