The tcp_check_send_head function in include/net/tcp.h in the Linux kernel
before 4.7.5 does not properly maintain certain SACK state after a failed
data copy, which allows local users to cause a denial of service
(tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted
SACK option.
