Description
A flaw was found in the Linux kernel's NTFS file system driver. When reading the attribute definition table, the driver does not properly verify that each entry fits within the allocated memory buffer. A local attacker could exploit this vulnerability by mounting a specially crafted NTFS storage volume or image, causing an out-of-bounds read that results in a system crash and Denial of Service (DoS) or potential information disclosure.
