Doc Text:
A flaw was found in the Linux kernel's NTFS filesystem driver. This vulnerability occurs when the driver processes an attribute with empty mapping pairs that have inconsistent highest Virtual Cluster Number (VCN) and size. A local attacker could potentially craft a malicious NTFS filesystem that, when mounted, could lead to a denial of service by causing the system to become unresponsive or crash.
