fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2
does not properly handle a failure of the add_to_page_cache_lru function,
and subsequently attempts to unlock a page that was not locked, which
allows local users to cause a denial of service (kernel BUG and system
crash), as demonstrated by the fio I/O tool.
