kernel is vulnerable to authorization bypass. The vulnerability exists as a missing check was found in the mext_check_arguments() function in the ext4 file system code. A local user could use this flaw to cause the MOVE_EXT IOCTL to overwrite the contents of an append-only file on an ext4 file system, if they have write permissions for that file.
