Flaw bug created to hold information about an old flaw we knew something about. For more details see the MITRE CVE description.
MITRE description: Some futex functions in futex.c for Linux kernel 2.6.x perform get_user calls while holding the mmap_sem semaphore, which could allow local users to cause a deadlock condition in do_page_fault by triggering get_user faults while another thread is executing mmap or other functions.
