Description
A flaw was found in the Linux kernel's NTFS file system. The file resize operation fails to acquire the proper synchronization lock while updating on-disk file attributes and sizes. A local user can exploit this race condition by accessing memory-mapped files during a resize operation, causing applications to terminate unexpectedly with bus error signals and leading to a Denial of Service (DoS).
