Description
A flaw was found in the Linux kernel's NTFS file system. A local user could trigger this vulnerability during error handling in Master File Table (MFT) write operations, where temporary kernel memory mappings fail to be released properly. Because these local memory mappings require strict ordering, the unreleased mapping corrupts task structures and can result in a system crash, causing a Denial of Service (DoS).
