The implementation of certain splice_write file operations in the Linux
kernel before 3.16 does not enforce a restriction on the maximum size of a
single file, which allows local users to cause a denial of service (system
crash) or possibly have unspecified other impact via a crafted splice
system call, as demonstrated by use of a file descriptor associated with an
ext4 filesystem.
